Well, you asked what he's planning on doing. We don't know. There really isn't much more we can discuss about it at this point, since we also have no idea what he's planning with the PT in general, much less ROTS. Hell, we know very little about what he's planning for ROTJ, other than that it's going to be extensive, and the ending battle will be expanded considerably.

Now, if you want to discuss ideas about what Ady could do with his Vader suit for ROTS, by all means go for it, but most of us aren't thinking anywhere near that far ahead and probably won't until at least TPM:Revisited comes out so we know the general direction that Ady wants to take his PT edits.
