I would’ve wanted Uncle Owen to be good friends or even close relatives in the PT. Owen could’ve been reserved while Anakin was all cocky or vice versa. If Owen was a charismatic dude who hung out with Anakin through the worst of times it would’ve been pretty sad to see Anakin drift to the dark side while Owen hopelessly watches and has no control, then it would be even more sad when you see Owen trying to protect Luke from becoming like his father did.

Another idea is that the clone army was actually on the evil end of the wars and there would be no battle droids. The Republic would be losing men by the millions and the tension would build incredibly for our heroes. In episode 3 the protagonists would figure out how to destroy the cloning system (like the death star) while Anakin and Obi-Wan fought. It would be infinitely more emotional.

Those are a few ideas, I’ll throw in a few more later. I’m considering doing my own PT Screenplays like many of you guys.
