I agree that it might not be worth the trouble to implement due to the relatively few number of people who would appreciate it. I like the tail number idea, though, that sounds easier.
It makes me think of another idea, related to the achievements. I think that there should be historical aircraft available to the top scorer in that aircraft type for a tour. Example: Right now, everybody has access to the Flak Bait B-26B skin. What if only the top scorer for the B-26B for a tour was allowed to use it for the next tour? If you had the highest score in TD 156, you have exclusive access to it in TD 157. If you don't hold onto your first place slot, then somebody else gets the honors for TD 158. For the tour that you've been awarded that skin, you get your name in lights every time you land.
"Kantro landed 5248 damage in Flak Bait of ~ The 47 Ronin ~"
If we ever get the B-17F?
"Kantro landed 10586 damage in Memphis Belle of ~ The 47 Ronin ~"
