unfortunately some of the features of that carrier can only be made by casting the part.
overall the main body of the carrier isn't overly complicated and could be machined, the issue would be that circular feature in pic#4(cylinder shame with 4 square notches around it). that feature can only be cast. i'm assuming that the 4 notches are there for the piston/cup to seat in. not having these notches may cause problems.
