I've been continually wondering more recently how they're gonna do it, and I think I may finally have a somewhat answer to that: they're going to use the alley in-between Beanpole Mountain and the Jurassic World queue, and to make it Hollywood's direct pathway to Donkey Kong. Think similar to Osaka's pathway to the entrance warp pipe.
With the removal of Soundstages next to Timeline Drive, I'm guessing the roadmap will require modification of timeline drive to flow better with the new campus being built right now on the hillside. That could allow them to open the door to expand the footprint to go a bit bigger than the 2 acres I am showing here (though i could be incredibly off kilter about this, and quite frankly, probably am).
