I don’t understand why they haven’t already started creating that extra space between RnR and the Animation Studios. I assume a lot of that is used for backstage areas, which could be relocated. Then they could be ripping it down and building there, all behind “closed doors” out of the way of park guests.
They need to get moving on the demolition now, whilst looking at all the options; all the options you listed could be back on the table (with modifications to account for the new area), along with new ones. But just get on with the demolition part now, not waiting another four years whilst they endlessly debate what to do next.
