Follow-up to previous post re: Ahriman Prospero box for 40k - disc?

So, it's been semi-confirmed that the Prospero box version can be used in 40k as both use a 32mm base for on foot. (He may look a little small, but that's fine).

Question - if I take the disc from my exalted Sorcerers box (40mm), could I kitbash to make him the Ahriman on disc? And be left with 3 footed exalted Sorcerers?
