Two thoughts on what looks like a great design:

- For use as a test chassis, how about emulating AndyMark's nano tube chassis and running power between the wheels inside the frame? That way, you could have every wheel slot powered all the time, making swapping drive trains even easier (just pull off one set of wheels and put on another!)

- If you want to use this for competition, keep the weight rules in mind. Swappable systems like this are really cool, but all of the hardware used in every configuration you bring counts towards your weight limit. So, if you plan to swap between traction and omni wheels at competition, you'll have to weight both sets of wheels with your robot, even though only one set will be on the robot at a time. See R03 in the 2012 game manual for specifics (it's been in the manual that way for years, I doubt the rule will change in the future).
