Yeah, there's 2 Barada's, and the vintage styled one is a whole different outfit... It'd require a new sculpt almost entirely for the POTF outfit to be made... A repaint would be a very half-hearted attempt I think.
On the issue of reusing VOTC so soon, I can see a reasoning behind not wanting to see those figures re-released in a basic format, I also think they're the best versions (at least 50% of them are) of their respective character so anything less would be just as annoying to see as well... VOTC Chewie with a real chain on a removable "dog collar" seems like a neat basic figure to me. I try to look at the original VOTC as $5 worth of figure with $5 worth of packaging... I'm not even a packaged collector 90% of the time, but those ones I had to keep at least the packaging nice and neat.
So to that end, I'd dig seeing VOTC Chewie out just because anything less is going to be sorta crummy quality. Hasbro should just save a buck, re-release a sculpt they have, slap some new crap on him... If they were REALLY nice they could include a tentacle arm or something weird... A pike maybe? The ROTS Chewie sorta sucks though so I'm not a fan of that one re-appearing.
