Can we get moderators together to ban abusive users from multiple subs?

There are some users that are downright abusive, especially when they get banned for being, well, abusive. The admins are very busy, and aren't always very responsive in addressing the issue. Would other moderators be interested in a sub or a service in which they can post, or check in to, to lock out some of the more abusive users? I am thinking along the line of reportthespammers, except that the result is that participating communities come together to lock out the offenders on a mod level.
