If the A-20 carries a useful bombload, it may carve itself out a useful role in the MA. Not many gunned bombers can do 300+ on the deck.
It also looks like the P-40E will perform well enough to at least be able to get kills in the MA, sort of like a slower Ki-61 with better guns. The A6M2 will doubtlessly see use in last-ditch field defence. The FM2 may see a fair amount of action off carriers; this plane had a reputation for being a great low-altitude dogfighter and as such might prove useful in the MA.
