I don't know that a 200 ft tower is necessary. I'm seeing it more of a situation where it goes up and down short distances, but also has the ability to go side to side to hit other shafts and scenes. Something like, leave load, go sideways to shaft 1. Go up shaft 1 then go forwards to scene 1. This also vacates shaft 1 for the next car. After scene 1, go sideways then backwards, then up shaft 2. Leave shaft 2 and go to scene 2. Keep zig zagging through 5 or so floors of shafts and scenes till we get to the top floor thats the department of mysteries. Have "things go wrong" with the globes, then drop down the last shaft to the Veil room and get arresto momentumed by someone who then sends us back to unload. Not a 200 ft drop that way, but could still get a good 50 ft drop out of it. Overall, it would mean more side to side and forwards and backwards rather than TOT's ups and downs, but would allow for more show scenes, and theoretically at least, more RVs going at the same time. Also, they could have more scenes than you could see in one ride making for re-rideability. Of course that means it would be a technological nightmare and probably cost prohibitive.
