Someone else came up with the idea of not even showing Vader in his suit in ROTS; the idea being that if you were to design the Prequels to fit with the Originals (so you could watch all 6 in order and not give away any surprises), then you would have to have Anakin called "Anakin" throughout the entire Ep I-III run and the last we see is him burning up.
That way when Vader makes his entrance in A NEW HOPE, you have no idea he is the same person until EMPIRE and JEDI. It would also help the "helmetless scene" in EMPIRE turn into a clue as to who Darth really is even before he makes his reveal to Luke at the end.
This would also mean that you couldn't show Obi-Wan on Tatooine giving Luke to Owen either, though it could be more dramatic to simply show a ship flying away with Padme's unnamed son, fate uncertain (if the Padme Organa idea is used, Leia would stay behind to continue the family line)
There is a Gary Kurtz interview link on the EMPIRE:R thread that I think everyone should read (as far as what JEDI "could" have been):
Key points:
(1) Vader was continuing in his quest to have Luke join him to destroy and replace the Emperor, but not so much out of conquest so much as a means of atonement.
(2) Leia was to be crowned Queen, as Luke wandered off to find his sister and become a full-fledged Jedi Knight (which would have been the impetus for the next 3 movies)

Bingowings:
I get the Lao Che, but what does Nurhaci reference? Also, while you wouldn't make it plain english, you could always have the bar name done in a way like the new PRINCESS BRIDE blu-ray (where the style is alien, but you can still read it if you look hard enough)
EDIT - ah, is that the Emperor in the container Jones gives to Lao? Heh, heh, that would be a good name to use...
Then again, you would't have to call it "... Bar" or "... Place"; you could just call it LAO CHE or JAR NURHACI (which sounds appropriately STAR WARS).
In that regards, maybe one could take some clips of Kenny Baker (say from TIME BANDITS or WILLOW) to use for a few brief scenes as the owner (JAR NURHACI) of the bar (to further reference Indy Jones' comments when he hands over the Jade vial)... you know, the little guy in the jar?
