Not only it's possible, but it's already this way! Maybe it's not too obvious at first, but the paper leaves at the left of the foruim's names are completely blank when there are no new posts, and a light shade of blue when there are (or you have unread posts there). If you come across some icons that you liek best, i could replace them.
