I think this could be a wonderful way to increase tribe memberships; I'm all for it!
Instead of on a right banner, though, I would put in on the front page beside the words "Front Page: 1 of 10". If it were to be put on the personal feed page as well, then I could see the list being beside the words "Feed: Subscribed Tribes". But of course, this is all just an idea. :)
