Great update to your work Dave... I'm liking the "ultimates" of Anakin and Vader...
If you wanted, a 2nd "Sith Eyes" head for Anakin wouldn't be a bad idea for Jedi butt whippings. Maybe a thought if you have an extra one? I dunno. These were hard sets to find for me. The only one I ever saw at retail was overpriced at Suncoast till they went under and I got it on clearance...
I like the fabric robed body myself, my complaint with it though is that, between the two bodies, the ROTS Anakin's is bulkier and more Vader-ish looking while the AOTC one is a bit thinner build.
That said, I like them both, and the poseability of the AOTC body with the fabric is great to me, but that's just my opinion... I like the poseability it gives you, not that the ROTS one is limited really.
The parts swapping on these is pretty seamless Dave, so I think you did a good job overall for what it is. Robe isn't a bad idea... Maybe a little work to make the hood lay down JUST right if you go that route... Otherwise, not much suggestion from my end. Nice work man, and good to see you still in the game.
