If you could somehow modify the kitbot to allow for something like this you could get by with only one robot plus an extra set of wheels. (I'm not even going to try to guess at how to do this, I'll leave that up to your team.) That's what we do when we do outside demos and we don't forget to switch wheels (which doesn't happen very often).

The 2014/15 kit robot will never be really quick and easy to change wheels. The quickest way would be to remove about a dozen #10 bolts (some with nuts, some tapped into churros) to lift the side plate on each side, swap the wheels (simple enough if the pulleys and hubs/bearings stay with the wheels), and put it all back together. A much simpler wheel swap would be to do wheels on a cantilevered axle. While it's not why we picked this chassis, our air cannon uses AndyMark nanotubes, which make swapping wheels a breeze: pull one 1/4" lug bolt and washer per wheel, remove the wheel, catch the key, put the key and new wheel on, and replace the lug bolt and washer. It would be even easier with tapped hex shafts, available COTS on VersaPlanetary.
