The Wildcat config is easy to put in Gerwalk, actually - leave the hip block, cockpit, and tail components in place, then deploy the legs and arms out of the body. The weapon mounts I see ending up as hip-packs, a la the 3D Maneuver Gear from Attack on Titan, or the Freedom's hip-cannons from Gundam Seed. True, this limits their field of fire somewhat, but no design should be perfect, and the Wildcat is pretty much guaranteed to be the 'quick and agile' counterpart to the Lightning (which was, I believe, easily the largest and heaviest successful day-fighter of the war), so giving it a narrower field of fire feels balancing.
The Dauntless'd be an option, but you could also just set it up such that bomber/command design isn't available immediately and doesn't show up until partway through the war. I think that that's what I'd do - have the Wildcat and the Lightning be the 'starting options', and then the Avenger is introduced, you're fighting the Japanese and their Shindens until some boss encounter over Tokyo, and then the war in Europe ends and you're sent there, gaining access to the Wurger and Schwalbe for the first all-out offenses against aliens on Earth, and then the Brunhilde and V-2 become available in time to ascend into orbit.
Or something like that. Doubtless I'm missing arcs.

"Yes, and it was glorious."
