It would be cool. It could however bring up a problem. And that is the ammount of time you spend in TL. For example you have stuff scaled up. (hattan is really huge along with stations etc...) You take the TL from Hattan to WP...the travelling in it would take AGES... not necessarily but if you scale stuff up you need to increase the distance between them to make it look like they are at the same distance yet they are bigger no?
(don't kill me if what i say now is completly retarded)
