I can't imagine that'll be the case - there might still be the elevator element, but I doubt the drop portion will be making a return,
Sorry should've clarified; I meant the lifts and effects/egg. I always thought the drop tower was removed or cannibalized for parts for The Dungeons.
If the drop tower is removed they could probably fit a temporary staircase in to get the bottom. There's not much going on in the upper area, if I remember right. Also they could potentially have the maze run out of the attraction and back into the lower level through a maintenance entrance?
