Would be impossible. If you lose that vehicle, you'll end up with a 12 popcap squad. Placing pop cap on specific units would counter the idea of having tanks switch crews for experience.
The best idea is to have tank crews have those abilities but be tied to their vehicle and only it until its destroyed (the tank crew cant stray 5m away from its tank until its destroyed or something)
Why impossible? Clearly possible. But then the question is it fair to give the US a heavy burden with tank crew pop caps:
One the one hand: It would be a real disadvantage for the US to have inf units with high pop caps. (and it seems the US have enough disadvantages with weak tanks and floppy AT guns that couldn't penetrate a bowl of KV-jelly)
BUT on the other, they have the advantage of being able to switch their vet crews between vehicles. That's a real advantage. Therefore there should be some disadvantage to balance it. None of the other army can switch vet between vehicles as the game progreses.
High pop-cap crews solve the issue of recrewing tanks to over pop cap level.
I don't see why a unit with such a useful ability as switching vehicles while keeping vet shouldn't have a downside to that ability like high pop-cap.
Yes but you have to start salvaging before you recrew. 
There is nothing wrong with this unit, just soviet fanboys whining L2p adapt L2p Lolz *smiley face*"
