Actually, we've done that a few times. Look up the "Outer Rim Wars" and you'll find a massive game in which several clubs competed, but in which there wasn't enough of a turnout from the Imperial clubs to stop the one Rebel club...
Although, to be honest, I think the EH could have stomped them had any effort been put into it.
