Hey, nice idea, would be hectic indeed.
I'll make the misison for you if you'd like. As you said Tomasz, it wouldn't really be too hard to script or make, just need to make sure everything is multiplayer friendly.
Send me a list of the choppers you want and on which side (unless it doesn't matter) and I'll do it. Also, tell me about any additional briefing/ overiews and cutscenes you might want.
If of you has played Gimbal's mission using his "Gimbal Planes" Addon, I reckon it would be a bit like that.
