Here's a thought that would probably be very difficult to realize, but since this is the "Radical" Redux thread I'll throw it out there: to me, one of the worst examples of CGI over-use, and one of the things that really sets the prequels apart from the OT visually, is that the clonetroopers are all digital. I wonder how much clone footage could be replaced with shots of guys in physical suits....even if it were just a few of the more static, close-up shots, it might make a big difference.
