I disagree categorically. I don’t consider any fan edit “definitive,” unless for me personally if I adopt one as such. They are inherently derivative and alternative. If that’s your concern, rest assured I’m not secretly supplying Lucasfilm with a master copy to overwrite the original.
And I don’t imagine going with layered dialogue for Palpatine for the entire movie. But I’d be open to considering using it in certain moments. Or maybe not at all, of course, but that’s the beauty of all this work. I kinda like the ambiguity of the Sith thing, and this would sort of channel it through a straightforward presentation.
