Not a bad idea, though I don't know if the need outweighs the work of installing yet another background app...for starters, the menu bar really isn't that much "noise" (at least on the left side, I do agree that the background-app icons seem to proliferate on the right)...secondly, on an iMac screen, or even a 15-inch Retina, my eyes have more than enough real-estate to dwell on without even noticing the menu bar.
