My first thought was where the pneumatic bumper attaches to the CRIO is not that strong. You don't want to be bashing other robots with it.
In terms of moving other robots. Your drive train has to be strong enough to hold the reaction force. If so you can just use your existing bumpers & drive train to push the other bots around. Oh wait some teams already to that.
Thinking outside the box is a good thing. Just realize that a lot of times there is a good reason the idea is not in the box to begin with.
