It's a bit risky, I'll give you that. Quirky and unusual. A 13-player game with only two scum in it and town masons is something which is a little on the townsided spectrum, but literally any change I could propose would throw the whole setup out of whack--additionally, while I would call this game a little townsided, I wouldn't call it horrendously townsided. It's certainly unusual so it's hard to get an exact metric, but I'd say in the range of ~57% townsided.
...The cutoff point being 60%, though. Means you should be good.
So,

Have fun!
