In STAR WARS, just like in Empire, I will be leaving most of the recomposited shots alone, unless there are other changes in the shot, such as noticeably repositioning the elements. I tested replacing the recomposited lightsabres but it didn't work very well, so I'll only colour correct them to fix stuff like Obi-Wan's sabre being purple in some shots and so on.
I can't yet say what I will or will not be changing, because I'll have to test some things out first and decide whether it works or not.
