Well, Walt Disney animation won't be overseeing the restoration. Lucasfilm is still a company, it's a subsidiary of Disney now, but still managed separately, but with Disney over them. Disney didn't just buy the movies, they bought Lucasfilm, so Lucasfilm would be the ones overseeing any hypothetical release of the OUT if I understand correctly. I wouldn't worry about the problems that plague Disney releases (I'm assuming you're mostly talking about the animated ones) are an issue with the Star Wars films.
