If I read your post correctly, you have to reduce the 4" cast iron to 3" ABS or PVC. There are of course space consideration to get the closet flange to the desired level, but that should be simple to do with adjusting the length of the ABS/PVC section. The joining of the cast and plastic should be done with a 4" no hub connector. From the hub, I'd use a short piece of 4" ABS/PVC, a 4" coupler with 3" bushing. Then the appropriate length of ABS/PVC to the flange, length appropriate to the distance needed.
