On purpose, no.

But looking at the way they handle their own films suggests that they'll probably just make a fake OTV out of a SE, the way they did with Beauty and the Beast or The Lion King.

I do prefer the original theatrical versions of both Beauty and the Beast and The Lion King. My guess is it was easier to for Disney make fake OTVs from the newly created SE Versions because both those films were sourced from the original CAPS Files. Even the Platinum Edition DVD of Aladdin from 2004 featured a slightly altered version of the film. Disney touched up some of the animation and backgrounds to make them work better for DVD.

Now for The Star Wars Trilogy the film elements of the Original Theatrical Unaltered Versions STILL EXIST. If all the existing film elements can be located then yes the three films could be scanned in 4K and fully restored.
