Without having a chainsaw on the front of your robot I think it would be great. I wouldn't worry too much about people thinking you were out to get them. In all reality most of the FIRST bots are over engineered to take quite a beating anyway.
Hopefully you won't charge up your pneumatics with 2000psi Liquid CO2 and send us into the roof.
They have quite a few topics over on the Battlebots Forum on, of all places, 'Delphi Forums' most of them flat out wonder why FIRST people don't like them since the two are very similar.
