I'd be all for a TL redo that involves gutting/replacing both Stitch and Laugh Floor (I've wanted them to remove Laugh Floor and use that space plus the land behind it to do an E-ticket like the Tron roller coaster) -- would be nice to finally strengthen the weakest looking land in the park. But if they were determined to keep the mechanics of Stitch, putting in a GotG theme wouldn't be terrible and could be done on the same timeframe as DCA to get it open for the new movie. And MK can afford to lose that ride to a refurb unlike DHS and ToT.
But I agree with
@marni1971 and others that I'd rather see them build a proper GotG from scratch.
