Those modules look beautiful, great work. Now that vex has released their 4 inch mechanum wheels I'm sure you could shrink them down quite a bit if you wanted. My only recommendation would be to consider swapping the traction wheels to the outside instead of inside positions. Since traction wheels are what you would most likely use during defense and pushing matches, it's advantageous to have them form the widest drive base possible. This will make your robot much harder to push when you have your traction wheels down. 148 used a similar setup this year with Omni wheels and they were very difficult to play defense on.
