Maybe a better option would be having some new material from another era, and not bleeding that TPM-ROTJ one for everything it has. Namely because it seems set in what happens(along with the fans seeing a majority of it), so why add anything new to it?
Though that might just be how Lucas works. Anything other than the movie period has to hope to slip through, and anything in the movie period? Its given a cliched story, characters we've seen before, and a dozen retcons making one think it just can't be decided on exactly how Anakin fell to the dark-side.
I'd love to watch, but that movie Era is getting old to me.
