I have tried it. Never again. You can't get to the part of the bulge that is under the ribs without removing them. Then you are getting into big money. If you decide to leave the part of the bulge under the ribs, you will still most likely pop the ribs loose while peening the bulge back into place, so you still have to relay them. There is always the chance there is a microscopic crack in the bulge that you can't see. Been there, seen that. Mine was discovered after removing the ribs.
It's a fool's game.
