One addition: One of the American's advantage is having aircraft radioes. The Japanese only have some kind of telegraph machine on torp bombers, and nothing at all for fighters and dive bombers, they have to use hand gestures to communicate.

Does letting IJN use American planes solve this? No, IJN carriers don't have radioes to communicate with aircrafts anyway, so even if you manage to let Hiryu use American planes, Yorktown still have this advantage in her pocket.
