Easy fix for Disney, just create a story with a time device and change everything to an alternate storyline.
Just like they did with Star Trek.
Or just make Star Wars set aside in a totally different era of the fictional Star WARS history altogether. I mean, Obi-Wan Kenobi stated that the Jedi Knights were around for 1000 generations, or around 25 to 30 thousand years, before the galactic empire.
