It may depend on if the customer wants "units" for the main arena, or for a possible historical arena.
The aircraft currently modeled are good for a MA because they are, for the most part, competitive with each other in their abilities. A higher % of "competitive" aircraft from WWII were arguably U.S. or German.
An HA environment, however, would require many new planes that would see little use in a MA.
A pacific HA, for example, would not work well with only 2 Japanese planes, both being fighters. Perhaps a Val or Kate and a Betty in addition to the A6M-5 and N1K would provide a minimum Japanese arsenal for a Pacific HA.
The Val or Kate, however, would likely see as much use in the MA as the 202 now sees.
