The Paramount Story is still there Yogi, it's just lost alot of the theming. It's not that great, unless they bring back the Sub's and make it look nice, now it's like the PKI ghetto.
I think just adding a train will help, touch up the paint on the cars a little, everyone cheers, the ride goes on a couple years and we get a new ride, sounds like a good plan.
Actually it's very possible you just have to have a longer pull-out. Superman is 400, only shoots up 310 or so, but still it doesn't pull to many G's, trust me it's entirely possible.
They aren't going to want your designs as you are not a coaster designer, building company. I think a floorless airtime wouldn't be that great. I would rather have an MF style ride, with a better layout.
