Why not run an ETO September 44-May 45 map and limit it to the 9th AF birds ie P38J/L, P51B/D P47D25/40, A20 vs LW birds 109G6/G14/K4 109A8/F8/D9 Ju88s and 110s
No one dominant bird, no overpowering bomber but enough to do some damage, enable Shermans, M3s, M8s M16s for the Allies, Sdkfz, Tiger and Panzer IV for the Axis. Let the ground pounders try and move the lines while the air guys support it and attack it.
You could do it 2 TAF RAF vs LW too if you took Spit IXs/XVIs, Tiffie's, Temps, Mossies and Bostons vs the LW set. Might want to enable 262s at a base or two for that one.
Use the Rhine map and fight the end of the war
