Is there something on similar grounds already in place?
You could probably do something with Drigg and a drupal forum where only "authors" and above had access to the forum and the drigg voting. Not sure how it works exactly though and I'm not sure how you integrate with MT.
You could run the eight blogs off a single drupal install too if you wanted to move from MT, but I assume that you don't want to do that.
