Well, you still have the issue of Leia appearing in the OT as an Organa--it is explicitly referred to as Bail as her father in ANH, right, not just one of the people Obi-Wan worked with? I could've sworn she said Organa. That would take some editing to not have people putting two and two together pretty quick. Because in ROTS, the other baby gets taken with Bail--but, hmm...perhaps you could cut out Bail's line of "My wife and I have always wanted a daughter." If you leave out the naming of Leia, then it's very ambiguous.

I do think it would be cool for Leia not to turn out to be Luke's sister, and then we don't have to cut out that hilarious shot with Threepio walking up to see Leia giving Luke a kiss in ESB. And, for the record, I was one who always rooted for Luke to end up with Leia. It does seem more in the spirit of the original, you know? That whole, old-school, serial thing. The main protagonist gets the girl. And it is also in keeping with Kurtz and Ford's wishes--that Han dies. I think it would have been cool if Han died saving the team on the sail barge, and then Luke goes nuts on the criminals. It's a shame there isn't the kind of footage to accomplish that...or is there? I don't suppose there would be. Han's pretty integral to the rest of the story. Oh, well. There's my little mini-rant about how things turned out.

But at least if we can make it so Luke and Leia aren't related, then that's a help.
