It really feels like this is solving a problem that doesn't exist, and as a result will hurt discussion. Additionally it assumes that people with 1,000 karma will sift through all of the comments to approve. Based on how few things get upvoted in the "new" section, I sincerely doubt that your members will sit on the "pending" tab waiting to approve.
We'll see how this plays out, but I'm probably done trying to comment here for now.
