I like the idea, but I too see the other side of the argument...
Most damage wasn't just pop it off and shove a new one on, most of the time it was take a week to get the damaged part off, order the new one, wait a month, get it, haul it out to the aircraft, then take a day getting it on... and sometimes it was past repair...
I think our .ef and get a brand new plane is more than enough.
