At the risk of belaboring the obvious, in order for AH to have historical match-ups, there must also be historical arenas.
Specific fighters were used for specific regions of the world during WW2 (ie; F4U in Pacific, P51 in Europe, etc.). Very unlikely to see this in its truest form due to the current senario in AH. Country would have to fly against country and each would have to do so in its own special arena (such as the Battle of Midway arena, or the Battle of Britian arena and so on).
I like he idea of historical match-ups, but its not fesible under the present circumstances.
