I like the core of this approach. But I’m still going to insist on keeping Rey’s parents good and her being hidden away on Jakku so Palpatine can’t retrieve his prize. I don’t think it’s a good idea to start changing more lines that were spoken on-screen with visible lips. The only problem with this new idea is that it’s hard to convey in simple terms. First, we’d have to explain how the Skywalkers were a reaction of the Force to Palpatine’s experiments because this is never stated in the main films (in fact the opposite is implied). And then we’d have to explain that Rey is the product of those experiments coming to fruition. The benefit of what we currently have is that both families would have the same origin (this being the latter), so we don’t have to explain ourselves twice. If that all did work out, though, we’d do the same thing as we’ve been talking about: “You’re his heir. You are a Palpatine” so we don’t have to absolutely demolish other scenes in the movie which refer to her as such.
