This would only happen if we get a Korean-era server. HTC has mentioned the possibility in the past, so I won't come flat out and say no. Just, not right now, the way the game is currently set up.
(BTW, THAT is when we will have a B-29 for sure.)
I'd love a Korean War arena... F-86A, F-86E, F-86F, F-84E, F-84G, F-80C, F9F-2, F9F-5, F2H-3, F4U-4, P-51D, AD-1, MiG-15, MiG-15bis, Yak-15, Yak-9P, La-9, La-11 and IL-10 for fighters and ground support. Add the A-26 and B-29 for bomber work.
Yeah, I'd love it...
My regards,
