Or a formation of TU2's could be used as Bombers, and a single TU2 with a limited payload could be used as attack/jabo. The plane set would be fairly evenly matched.
Spit16 vs La7
Spit8 vs yak3
B26 formation vs Tu2 Formation
Mossies vs Single Tu2
The Soviets would hold a slight edge on Fighters, where as the RAF would have a slight advantage in attack/bombers.
The late war uber rides may also attract more people. As for the ground war, seing that very few people decided to engage upon that aspect during the previous scenario I can't imagine that being overly popular in any future scenarios.
I though about the VVS vs IJAF matchup in 1945 Manchuria, the plane set seems unbalanced in favor of the VVS. I believe the 108 sentai was 50% Ki-44s and 50% ki-84s. We don't have Ki44s and 84s would get eatin alive by the LA7s
