Skurj,
I like the idea. As Eagler said, "Variety is the spice of life" and this is what makes the CT different from the MA because the plane sets and historical basis are changing constantly. However, with this particular setup that you mention, you'd have about 70% or more of the same aircraft that are flying the MA. I agree with Lephturn in that what attracts me to the CT is the historical plane matchups. When I fly an F4U, I do not want to be dodging LA7s and 190Ds like I would in the MA. This also holds true with me with a good "what if" scenario. When Germany and Japan were defeated, where was the biggest tension in the world? I would think a good USA vs USSR CT would prove interesting. Say, USA launching from bases in Germany or Japan. Maybe for once LA7 pilots would find themselves in an environment (altitude) where they are not king-of-the-hill when going after high level bombers. However, I'm sure they'd quickly dive to 12,000' or below and there'd be some very good medium-altitude and low-altitude fights.
One thing I think could really improve participation in the CT is if it could use its own particular paint schemes. The MA can use standard schemes but say if the CT were holding a desert scenario, the planes would have tans and off-yellow paint schemes. Beyond that, we really need more aircraft and I vote early-war Pacific. (I really feel strongly that Aces High concentrates on Europe too much, but that's just me.)
(I'd also like to see a water map and have CV vs CV only battles. Maybe uncapturable land for ports so CVs can respond [maybe a heavy bomber base too.] You'd have to locate the enemy CV and then conduct massed attacks against it. I dunno, seems thrilling to me.)
