Well, I've always got fun ideas for these movies, but I don't have any capacity to fix them myself. I hope someone will take some of these ideas and run with them, perhaps a full six-film approach to their edits, complete with preserved secrets and maybe even those flashbacks. Who knows?

Thinking back to preserving the secret, if it could be shown that Anakin is still alive (crawling up the lava river bank), and that the Emperor sends Lord Vader to Mustafar to "take care" of Anakin (line lifted from Sidious talking to Neimoidians with slight alteration, if possible), then maybe there'd be some solution. We would wonder who Lord Vader is and what Sidious means by this. We'd think Vader would be killing Anakin, but in the end we'd learn that really Sidious was providing a suit for him. I dunno, that sounds kind hokey.

Also, I'm agreeing very much with removing the name Skywalker, but also doing the Q2 thing where Anakin seems dead and we never see him become Vader (except maybe through later flashbacks). Of course, new problems arise, such as the relationship with the Lars family and the surprisingly good ending for ROTS looking at the Tatooine sunset (that would probably have to be included in a flashback as well). I don't know. It's a fun problem to try to reason out. Maybe in the end we'd have to settle for exactly as Q2 gave it to as and as timdiggerm explained: Kebobi is manipulative, but we don't know the extent until ESB.

Gosh, I'm just thinking in realtime here. Maybe a pentalogy is the way to go to preserve the secret. 1-2, 4-5, and a 3/6 hybrid with lots of flashbacks. Oh, what fun!
