Really, the only difference in penalties is how many indirect Ts the head coach gets. For fighters, he gets one for each bench player who actually fights. For non-fighters, he gets a total of one for all bench players who go to the court but don't fight.

If only one bench player gets up for each team, it's not going to matter, penalty-wise. And if you don't offset the penalties, you have to give two free throws to each team.
