I was just thinking along those lines today. The trouble with MA missions, is that many of the people want a payoff. They need to see the base captured for it to have been worth it.
The people you need to target are those that want to fly large hi alt buff raids, that dont need to capture, simply go on a mission to bomb something. Then you need to find the types who enjoy keeping those guys alive. Lastly you need people who like to kill bombers and their escort. The target itself is simply the stage.
