The track is pretty thin, probably even thinner than a metro wheelbase. Even if I could get that to work (since the drivetrain is pretty small on the cart) it's geared so slow with only one gear (and I doubt it's CVT :-P) that i don't know if I could convince it to go as fast as I want nor up hills quickly enough to be safe. I will look into this a bit more in depth. I'd still really like to know if anyone has ideas on the optimal transmission for my application.
