vinkman,
Disregarding the false claim that the Ki-43 was slower than the A6M, you should consider things beyond what happens when you something in your F4U. Compare what happens when an A6M meets a Ki-43, or a B239 or a Hurricane meets the Ki-43. All of those are different fights than when they meet an A6M. The Ki-43 is such a core aircraft from WWII that what is needed is not one Ki-43, but three of them, the 315mph Ki-43-I, 330mph Ki-43-II and 365mph Ki-43-III.
The P-63 is a footnote and should be a very long time in coming to AH.
