Very good idea I must say. Those ball castors work really well. Team 108's 2005 robot had 4 of them on there. It was easy to use and it worked.
For Jeff's purpose I would suggest what John has posted above. Omni wheels, or take the treads off of the wheels, or even use the plastic pieces... they work great.
