I've had a similar idea for the MagLev to replace the peoplemover. It doesn't necessarily have to be something directly out of Minority Report, but revamp the peoplemover so it has more futuristic, faster moving vehicles (yeah yeah, I know... Rocket Rods.... etc..), and maybe somehow switch up the track a bit to allow for a vertical section.
I loved that scene in Minority Report, but somehow I doubt they would let guests jump from car to car. Just a small safety / insurance issue there!
