Thank you guys. Rattfink, that photo of Nooy's Hellcat is interesting as the kills and squadron art would line up nicely with the patch on the fuselage of the default McCampbell skin. Its a pity I can't see the squadron number completely, if it was an "8" it would mirror perfectly but its probably something like 13 or 38.
Roger, there's a Hellcat with white ailerons already in the game, from VBF-12. Is that the one you mean?
