I know this is an old post, but I actually really wanted to do this for a trio era game, but I am already co-modding a successful game and didn't think I could do it justice right now. I love that you used the term "secondary house" because waaaaay back when I ran school games I asked for this on trio era applications to avoid too many stereotypes in personalities. If your game gets running, I'd be interested to see how you handle it in a second-generation of characters. It sounds pretty unique. Good luck. <3
