Well I don't see how it couldn't work, I was just brousing through the archieved RP's on houseeros and I found one that had about 17 different subforums and they seemed to work out fairly well except my guess is that a few too many people lost interest and the whole tthing fell apart. Which is one of the downsides of group rp, the more people there are the more fragile the balance and technically the more likely to fall apart.
