IMHO, I think if this were to be implemented... it would not affect the perk points spent on aircraft... if the aircraft is lost, the aircraft is lost.
The only benefit I could see would be if a pilot were downed in enemy territory, and rescued, instead of him receiving a capture, he could could at best receive "bailed successfully". Thus the downed pilot would receive only a 50% reduction to his kill points for that sortie instead of a 75% reduction.
However, the guy piloting the rescue aircraft would receive a perk bonus of some kind for getting the pilot back safely. As an additional bonus maybe the downed pilot would have to to split the perks earned on that flight with his rescuer.
Example, I'm flying a P-51B and get 10 kills, accounting for 25 perks but was shot down in enemy territory. I'm successfully rescued so I would only receive 12.5 perks for that flight, and the rescuer would receive 1 perk plus the 12.5 I split with him for getting me home.
Just brainstorming...
