It is an interesting idea...

I can see why it would be useful for people reverting bad edits, but I'm not convinced that that's enough to make it worth the time and resources it would take to set it up and run it. It wouldn't be something that could just be set up and left to run by itself, the group would need staff help, just as other volunteer groups do.

So I think this is an idea for us to keep in mind, but not something we can do at the moment.
