I have a better idea for January's BOTM to ensure more variety on the boards before having another IRL themed BOTM: Stock Unrealistic Heavyweight with Component freedom allowed. Seeing how difficult it is to build a Stock, how about making it easier by allowing Component freedom like what enigma did for Robo Rasslin.
You can just use the tool for BOTM on a normal bot. The internals aren't checked for a tournament. If you don't abuse ra2cf you won't get caught.
-----------------------
Considering that the next IRL BOTM has a wacky building rule, the less realistic BTOM should have an odd theme too. A few ideas
1. Robots must have a Steelyard Dogs' Plow
2. Full body spinner (Thundercloud style, full body VS, etc)
3. Sawbots
4. Pyramid shaped body (either via the chassis or the components)
or
5. Robots must use a prebuilt chassis
