That's a good idea...
And it could be a bit of challenge to decide when the mission is complete ... And to have the EMG generate dogfight maps? I don't think that'd work, and to edit each generated Coop to convert to DogFight? Lots of work ...
Maybe focus on shorter coops, and really focus on Teamplay, so only one side, and use a theme for an evening, kinda like a very short coop campaign - I am thinkin' here from what the EMG can deliver us: On one Map (ie. Stalingrad) it can give us like three 'fronts' ie three different stages over the war over there.
So, maybe two missions per front, switch to next stage, two more. All the time using a similar set of aircraft ... like for Stalingrad - Axis: 109 + 110. Thus fill one session of cooping... Next session... Rheinland map, Allied... P51 and P38 ... and so on...
I dunno, really.
