The basic rule of sequels is you're stuck with what went before, no matter how much you hate it, but you can explain how things were not as they seemed, which some writers call spackling.
If I was in charge of the StarWarsVerse, I would reveal that to consolidate power, the Empire and the Jedi colluded in a hoax: they taught that only people with midichlorians could be strong in the Force to hide the fact that everyone could be—what really matters is training and commitment. Why, you ask, would they do that? To have an effective monopoly on the Force. Why would the Republic continue the old lie? Because its rulers, like all rulers, want people to be content rather than free.
