Purely guessing on what the team may end up doing but going by the concept art you can be almost assured that they want to do a F4F Wildcat (-3 and -4 versions make sense), SDB Dauntless, TBD Devastator, the A6M2 "Zero", D3A "Val", and B5N "Kate" you have a pretty solid starting line-up. There's also a concept shot with the Buffalo and a PBY so clearly the goal is to extend as much as possible.
There's a pretty obvious set of chances to progress the line-up from there to Guadalcanal, New Guinea, up the Slot, and on! But... one thing at a time!
