We can all hope for sure.

From a technical standpoint, based on the minimal level of effort Disney has put into the release of earlier films, I would be surprised if they had plans for extended editions across the board. Extending Star Wars Ep 4 would be rather dubious and not yield such good results (we already have limited scene extensions/additions in the Special Editions). As much of a rush as TROS was to release, my guess is the best we would get is some actual deleted scenes, maybe. And the idea they would tinker with the OT to digitally replace Alec Guiness seems a bit far fetched. They will be generating revenue with the Kenobi series and The Mandalorian Season 2-- things like this will probably be their focus.
