Sorry about being so negative, but I just don't see it that way. I know you've put in a lot of work on this and is is sure as heck easier for me to sit here and deconstruct your effort than it was for you to get up and make the effort to put it together.
Maybe I'm way off base and the community will rise to the occasion, but I just can't see a guy who wanted to fly P-40s or F4F/FM-2s sticking around and flying A6M2s. People seem pretty set in their plane choices. I didn't sign up to AH to fly Axis aircraft, but I usually do if I'm not in the Mossie simply to even the numbers. I signed up for Spitfires, something I never fly now. I was willing to switch, whereas most, as demostrated by the recent ENY hoopla, are not at all willing. What I'd expect is if the numbers of IJ pilots you need do not show up and you ask Allied pilots to switch, most would either wait for the other guys to switch or just log out. It perpetually ends up being the same few guys who are willing to do what is best for the game who don't get to fly what they want.
To me, based on what I've read and what an F4F pilot said in my presence, I really feel strongly that the the F4F is modeled quite optimistically. I know that my recent attempt to get an opposition squad going in the CT garnered no interest. I had two people who actually were interested.
Heck, maybe I'm just in a pessimistic mood. Not that that excuses me crapping on your scenario. Now I'm starting to feel obligated to sign up to make up for it.
