i think you can. but i have never tried and have never seen it done.
it would be pretty damn complicated.
you would need to figure out how to merge code for drivable vehicles with the stock maps.

the tankbattle map would give you the code to make the tanks work.
but because the tanks don't already exist on the board, you need to spawn them in your scripts.

i don't know your experience, but this is definately an advanced mod.
