I think if the comic could be made so as to be made by the "newbies" (those who came in the last year to Tris), you may have better luck. It may lack some good art, but it would be the "Trisphite's" work, and could grow from there.
Might I suggest a look-around?
Several interesting things were present in Trisphee, but their organizers became too busy, and the threads died.
I've been trying to create interesting things to maintain/attract Trisphee users. The Library (A growing database of decent reference websites and Ebooks ranging across many topics) is the first "success" (Interestingly, I made it mostly for my own use).
