Personally I think a GV oriented scenario ought to have a reinforced company for each side of vehicles, 2 flights of fighters and a flight of tank hunters.
No rules regarding air-ground, ground-air fighting.
Very basic break-down would be as follows:
Ground commander's vehicle
XO's vehicle
FAO's vehicle
1st, 2nd, and 3rd tank platoons.
Air defense platoon
Supply section.
Reconnaissance platoon.
High performance fighter aircraft flight.
Endurance/recon aircraft flight.
Close Air Support flight.
That gives you provision for about 40 players on each side, which can be a fairly nice little brawl.
A quick and easy setup if you will that could be run as a test-bed to see if a far more GV oriented scenario would be popular enough to merit a larger force.
This would also give you the opportunity to test to see just what effect a lower ratio of vehicles -> planes does, as well as give ground commanders a tactical consideration of sacrificing tanks to knock out enemy ADA before calling in the tank busters.
I'm probably just daydreaming over here of putting together something that operates even 1/10th like an actual mechanized unit, but the air war did evolve out of supporting the ground war.
Maybe if we put the aircraft into that role and limit their numbers a little more it would make them vastly more important.
If you can neutralize the ADA and retain your air cover, even if you're out of heavy ordnance 2 or 3 aircraft providing real-time data to the ground and tossing tracers towards enemy tanks could very well turn the tide of a battle.
I'd give two lives at 15 minute death-timers to the air crews, who in the meantime could be running as the supply section or such.
Add in a significant travel time for the ground forces to open up the intelligence battle and I think it'd be a lot more in-depth than the previous GV scenarios.
I'm thinking of DGS here where the scouts were perhaps the most important part of the German force. Finding, reporting, and sticking with the American bombers allowed the German side to orient their strike force properly for the best punch possible.
Getting that kind of turn-out for a GV oriented scenario would be awesome, to have 2 or more companies operating independently and/or under the direction of a Bn commander.
But I think if we want to make this really successful we need to start out smaller and organise at least one smaller scale test-scenario to work out the kinks for organizing the ground fight. Especially in regards to what terrain to use, how to spawn in, how to decide objectives, what vehicles, etc. etc. etc.
