I would say we have a tremendous opportunity with the Normandy 2.0 map in that we have what was essentially a static front line map for over 4 years. With the right aircraft you can run Battle of France, Battle of Britain, Circus and Rodeo missions, early Allied bombing raids, pre-invasion bombardment and Allied advance from June-August 1944. To that end I think there are so many aircraft that would fit that bill.
Spitfire Mk1, Spitfire Mk V, Hurricane, He-111, Ju-87, Bf-109E/F/G,P-47 Razorback, P-38 F/L, P-51B, B-25, B-26.Beaufigther, Do-17,Defiant.
To pick from this list and several others I have forgotten about. I would probably choose the BF-109G first simply because it fits with the aircraft we have available for the mid-1944 missions, but truthfully we could use all of the aircraft above.
Sadly producing the aircraft with the level of fidelity required for DCS tends to have a much more disjointed approach.
