I know people have already posted this, but it was confirmed in a digital bits interview a few months ago: (https://tr.im/1c09C)
"We’ve essentially confirmed that Disney’s current 4K scan of the film is the most recent revised version (essentially the latest “special edition”), not the original theatrical edition. What’s more, Disney’s director of Library Restoration and Preservation, Theo Gluck, held a special event at Ohio State University’s Wexner Center for the Arts last night, a presentation called Animation Restoration at Walt Disney Studios. Gluck was asked there about Star Wars and reported that the original cut negative for the film currently exists in its “SE” configuration only."
When asked if there were any plans for an OT restoration, the answer was no:
"Disney’s director of Library Restoration and Preservation Theo Gluck, and 20th Century Fox’s Senior VP of Library and Tech Services Shawn Belston have confirmed to the outlet that no such work on a reconstruction has begun."

More recently, about 16 minutes into this interview, Kathleen Kennedy seems to rule it out:

So, it looks like the will just isn’t there.
