We have plenty of tickets in CO:OP anyways, so why not?
The idea of mine I told you today was about a cross-faction-custom-weapon-loadout thingy, meaning as an officer you would be able to chose your own pistol; or to have (let's say) a spotter with a rifle of choice plus the radio and nothing else (no bandages, ropes, knives, smoke grenades, etc.). Or (let's say) an Anti-Tank guy with nothing but his launcher and 3-4 ammo boxes in his inventory.
Obviously that will never happen.
Airlift sounds cool -- I don't think there's enough factions to utilize that method though, even if we ever made it simple, just like in Battlefield 2 where vehicles fall from the sky.
Re-arming in air is something that you will find in Ace Combat or some modern RTS games and should never belong here.
The biggest problem in this game right now is the air-to-air and surface-to-air combat which is simplified beyond my imagination.
