What I don't see is early Eastern front i.e. 1941 Summer,
Barbarossa one of the most important air campaigns of WW2 that resulted in total air superiority for LW on eastern front.
I think today we do have very relevant plane set:
Axis: 109E-4 and limited 109F-4; bombers Ju-87, He-111 & Ju-88; tanks Panzer IV with short 75mm canon
Allies: I-16 and limited Yak-7b; bombers IL-2; Tanks T-34
I want to note that ideally we need 109F-2 and Yak-1, LaGG-3 and MiG-3... but we don't
109F-4 is later version with more powerful engine that wan't avalible in significant numbers in 1941
Yak-7b is also 1942 version but in terms of performance it was still close to Yak-1
So I think this plane set would be very representative, also it is later that exactly 1941 it is good enough and balanced match I-16 vs 109E and Yak-7b vs 109F-4. Same for tanks and bombers.
11. Operation Unthinkable. A "what if" scenario of Soviets vs. RAF.
If you are doing "what if" so I'd suggest what if Korean war was started at 1946... i.e. La-7, Yak-9U, Yak-3, Tu-2, IL-2 vs P-51D, F4U4, Spitfires XVI/XIV. It little bit more historic concept (BTW on the beginning there were indeed La-9, IL-10 and Yaks)
Of course 1948 Arab Israeli war* would be cool as well ;-)
