As long as you discriminate based on performance and behavior, and not on their "disability" status, I don't see a problem. Document and make public the requirements early on, regularly emphasize that those who do not meet the participation standards do not travel with the team, and stick to the policy regardless of any complaints when someone fails to make the cut. You might have a tough first year, but it will perhaps weed out those who aren't serious about the goals of FRC, and it will definitely impress on everyone else the fact that actions have consequences.
