I honestly shut Star Wars edits mostly out of my mind when this stuff first started popping up because the possibilities were just too overwhelming.
For the sake of sanity… I think it would be wise for faneditors with pre-existing edits to ONLY revisit ideas that were like 98% completed towards what they wanted it to be, to help give it that extra 2% to complete their vision. And for any new edits, to only rely on AI voices to help implement a greater change elsewhere.
Otherwise, it’ll just be a crapshow where half a movie will be AI dialogue and it will lose the DNA that made it unique.
Once you start down the dark path, forever will it dominate your destiny. Consume you, it will.
