Maybe some clues to the tower structure from the Ride to Happiness. Just scale up this A-frame concept front and rear. The track might go straight up the front A-frame, peak over it, then ascend up to near the peak of the rear A-frame and curl around it. It could also mean that the train and track actually go the full 375', being on top of the A-frame. That, with the inversion up top, would be incredible.
