The prequels are too ingrained in the public consciousness to simply remake them without a lot of issues. I think the best idea, if they went the prequel route, would be to make a trilogy that happens concurrently with the Lucas prequels and exists in the same continuity, but focus on the smaller players in the Clone Wars. Episode 1 starts in the middle of the clone wars, Episode 2 happens alongside ROTS, and Episode 3 depicts a galaxy ravaged by war under the iron fist of the Empire. Focusing on normal people rather than Jedi would make the Droid/Clone armies actually threatening, and it could explore some new droid design space since there were many separatist factions. The films could reference the political situation, but never more than happened in the OT. The Jedi remain largely mythical, the story takes place on the fringes of civilization like in the OT, everyone’s happy.
