Depends whether you want a Japanese bomber for the MA...if you do, the viable list becopmes very small indeed.
Most likely we'd end up with well modelled and fine looking plane which would be used about as often as the Ju88 and that's a rare enough sight.
One plane that would cut it is the Ki67 Peggy: An Army plane, but with torpedo capability it would also be valuable in 1944 scenarios. According to Francillon;
"Without bombs the Ki67 could easily make loops and vertical turns, and it's controls remained smooth and effective in a dive at 373mph IAS."
Some form of carrier attack plane would also be a worthy addition, the type depending on whether you wanted a 1942 or 1944 battle.
For the latter a B5N and D4Y, Val and Kate for the former.
I've always thought it a shame that HTC builds a superb, player-controllable naval element into the game, yet we still lack the planes for a PAC scenario.
