WWII autocannons that weren't the mollins gun tended to trade muzzle velocity for projectile weight, so as the caliber gets larger the comparative case volume gets smaller.
that being said it's entirely plausible to build an aircraft wing capable of mounting such a weapon, but at the cost of dramatically higher airframe wight with a consequent loss in maneuverability
What if you instead mount it inside the nose of the plane? To make room you could do what they did with the Bell's Cobras and instal the engine in the center fuselage behind the pilot.
That's what I am doing for my ground attacker of the period. 40mm something-nasty in the nose and than a pair of 20mm's in the wings. But for my fighter I was contemplating a setup with 1x20mm in the nose (BF-109 style), 2x20mm in the wing roots and 2x7.5mm through the prop. And I am mainly probing if I'd have to use a different 20mm for the wings than I have to for the motorcannon because I know that the engine mount can be as far up as 30mm no problem but I am not a huge fan of having two different trajectory weapons in the same caliber.
