I usually keep 3 Catchers for 13 or 14 players. Since I prioritize defencive roles over offencive (Humans can attack, but for winning they need to work hard in defence), my Catchers are defencive: Guard and ballsacker (Wrestle+Stripball+Dauntless). There are only 2 places for Catchers not on LOS in defence (8 non-LOS positions, that would be 4 Blitzers, 2 Catchers, Kicker and Dirty Player; with Ogre on LOS, which is questionable), so the third Catcher is usually a generic benchwarmer.
I wouldn't normally do Catcher-balcarrier without +AG, or specialized oneturner without +MA. But it is exactly your case, so why not to try?
