         3 . The system of  claim 1 , wherein the plurality of first retention features and the plurality of second retention features are a plurality of interfacing shoulders that interface to provide load transfer from within the slip hanger or packoff to the oilfield equipment. 
     
     
         4 . The system of  claim 1 , further comprising:
 a top plate;   a seal; and   a plurality of fasteners to retain together the top plate, the seal, and at least the plurality of inner bowl segments prior to use in the oilfield equipment.   
     
     
         5 . The system of  claim 1 , wherein the plurality of inner bowl segments comprise a first thickness between the inner side and the outer side and wherein the singular outer bowl comprises a second thickness of an outer wall, wherein the first thickness and the second thickness are based at least in part on at least one diameter of the oilfield equipment and a casing in an application of the slip hanger or the packoff. 
     
     
         6 . The system of  claim 1 , wherein a plurality of fasteners retain together the plurality of inner bowl segments by a pulling force on the plurality of inner bowl segments and by a squeezing force on a seal that is between the plurality of inner bowl segments and a top plate. 
     
     
         7 . The system of  claim 1 , wherein the outer bowl comprises a beam structure having a plurality of flutes and splines in an inner side of the slip hanger or the packoff to enable transfer loads from a pressure above the slip hanger or a packoff to a load shoulder of the oilfield equipment. 
     
     
         8 . The system of  claim 1 , wherein the plurality of inner bowl segments is replaceable to adjust the slip hanger or the packoff to an application diameter associated therewith. 
     
     
         9 . A plurality of inner bowl segments to support a plurality of slip segments on an inner side and to be supported by a singular outer bowl on an outer side, wherein the plurality of inner bowl segments comprise a plurality of first retention features to enable association with a plurality of second retention features of the outer bowl, wherein the plurality of inner bowl segments are part of a slip hanger or a packoff to be used with oilfield equipment. 
     
     
         10 . The plurality of inner bowl segments of  claim 9 , wherein the plurality of first retention features and the plurality of second retention features are a plurality of interfacing shoulders that interface to provide load transfer from within the slip hanger or packoff to the oilfield equipment. 
     
     
         11 . The plurality of inner bowl segments of  claim 9 , wherein the plurality of inner bowl segments is replaceable to adjust the slip hanger or the packoff to an application diameter associated therewith. 
     
     
         12 . The plurality of inner bowl segments of  claim 9 , wherein the plurality of inner bowl segments comprise a first thickness between the inner side and the outer side and wherein the outer bowl comprises a second thickness of an outer wall, wherein the first thickness and the second thickness are based at least in part on at least one diameter of an oilfield equipment and a casing in an application of the slip hanger or the packoff. 
     
     
         13 . A method for a slip hanger or a packoff to be used with an oilfield equipment, the method comprising:
 determining a diameter to be associated with an application of the slip hanger or the packoff;   determining at least a plurality of inner bowl segments associated with the diameter; and   providing the plurality of inner bowl segments to support a plurality of slip segments on an inner side and to be supported by a singular outer bowl on an outer side, wherein the plurality of inner bowl segments comprise a plurality of first retention features to enable association with a plurality of second retention features of the outer bowl.   
     
     
         14 . The method of  claim 13 , further comprising:
 providing a load shoulder of the oilfield equipment to support the singular outer bowl for the slip hanger or packoff to be used with the oilfield equipment.   
     
     
         15 . The method of  claim 13 , further comprising:
 providing a top plate and a seal to be associated with the plurality of inner bowl segments, the plurality of slip segments, and the singular outer bowl; and   retaining together, using a plurality of fasteners, the top plate, the seal, and at least the plurality of inner bowl segments prior to use in the oilfield equipment.   
     
     
         16 . The method of  claim 13 , wherein the plurality of first retention features and the plurality of second retention features are a plurality of interfacing shoulders that interface to provide load transfer from within the slip hanger or packoff to the oilfield equipment. 
     
     
         17 . The method of  claim 13 , wherein the plurality of inner bowl segments comprise a first thickness between the inner side and the outer side and wherein the singular outer bowl comprises a second thickness of an outer wall, wherein the first thickness and the second thickness are based at least in part on at least one diameter of an oilfield equipment and a casing in an application of the slip hanger or the packoff. 
     
     
         18 . The method of  claim 13 , wherein the outer bowl comprises a beam structure having a plurality of flutes and splines in an inner side of the slip hanger or the packoff to enable transfer loads from a pressure above the slip hanger or a packoff to a load shoulder of the oilfield equipment. 
     
     
         19 . The method of  claim 13 , wherein the plurality of inner bowl segments is replaceable to adjust the slip hanger or the packoff to an application diameter associated therewith. 
     
     
         20 . The method of  claim 13 , wherein a plurality of fasteners retain together the plurality of inner bowl segments by a pulling force on the plurality of inner bowl segments and by a squeezing force on a seal that is between the plurality of inner bowl segments and a top plate.
