Sorry but going to have to disagree. Damage is not always simple and there will still be winners and losers. What if a driver has a scuffed rim - could fail at any time as we have seen many times in the past, but they get a free tyre stop if they replace it. Or as in Valencia Hamilton pitted to replace his damaged front wing and got a free tyre stop out of it? Or does he need to pit twice, once under the safety car for the nose, once for his tyres after the safety car is released!? If so then surely this would encourage drivers to stay out with damaged cars, understeering around the track even at safety car speeds, just because they don't want to have to pit twice. You still have a lottery despite your intention of avoiding one, you just change the way the luck of the draw is decided.
If all drivers are driving to their delta time and the leader is picked up by the SC at the end of the pits then there can be no large advantage gained or lost and there's no reason for subjective damage checks. The only reason Alonso lost out so badly was because the safety car held him unnecessarily. If he'd been released then at most he would have lost a few seconds to Hamilton and would have likely kept his place.
Edit: In fact thinking more about your ruling, you are actively encouraging those drivers with damaged cars to race back to the pits as fast as they can in order to have their cars fixed, as they're the only ones who can gain an advantage through pitting. Are you really sure that is a good idea?
