Homebrew Mii editor/deleter

Is anybody aware of any homebrew or any other method for quickly deleting Mii's from a Wii? I realise I can drag them individually into the bin using the Mii channel but it's horrendously time consuming (not to mention boring). Basically, my ex's kid made enough Mii's a build a small army and the Mii plaza looks like a scene from Spartacus.

Ideally what I'm looking for I guess is something similar to AnyTitleDeleter than can list the Miis and allow me to selectively delete them. I'm reasonably sure it doesn't exist as homebrew (yet?) but wondered how feasible it is as an application and if any of you folks could think of a solution that didn't involve me sobbing gently at the TV for over an hour :)

Thanks.

It probably could be made, I know there is an app for extracting and installing miis, i dont see why there couldnt be one for deleting them. But afaik, there isnt one yet.
