I know some have said that they see flaws in Tatooine as the setting for the first segment of ROTJ, for various reasons.

If they were rendevouxing there at the end of ESB, what took them so long?
It shrinks the universe.
The Yuma desert is not as dynamic as Tunisia.

But there's no reason Jabba has to be on Tattooine. Is it possible to turn Tatooinne into another planet? Perhaps re-matte the sky with weird clouds, or make it an odd color, tint the sand to make it red maybe.

The crawl would have to be re-done, as well as cutting Luke's line "I grew up here you know." Other than that the changes would just be cosmetic.

I don't know if this is doable, or even necessarily a good idea, but it occured to me watching ROTJ this weekend.
