The problem is that both make use of quite a bit of work that was done on the 2011 masters. (Clips from Revisited, DeEd, FX done for this project, etc.) Those clips would have to be adjusted to fit with the new masters. It’d just have to be a whole new project, and there’d been to much already done. See what Ridley did with the Falcon scene in ANH, for one thing.
As long as all three feel consistent enough, I’m happy with them as the SE option when I wand that. And I love what’s being done to restore the OOT from these new masters when I prefer to watch that.
