How about casting a blank then pressure (friction) turning the OD. Mount pie shaped top jaws on your chuck. Machine a recess in the jaws to match the OD of your part. Face one side. Flip the part and do all the ID work except the pockets. Mount the chuck with the part still in it on a rotary table on the mill. Tilt the head of the mill and cut the pockets with an end mill reground to the correct diameter and with a flat bottom.
If your chuck does not accept top jaws you can machine a ring of steel so the ID matches your blank. Split one side of the ring. Hold the ring in your chuck.
