How would it, if added, redress the balance? In the MA it would be perked and in ToD or the CT it would never see use. That doesn't address the balance at all.
A better way to redress the balance is to figure out why Luftwaffe fighters don't match their reported ease of use and provide the data to get them fixed.
Another method would be to get ammo belts that tracked individual round types, eg, tracer HEI, HE, HE, minen, tracer HEI, HE, HE, minen, ect, ect instead of just a generic average of them.
That would be a way to address the imbalance without resorting to "Wonderwaffe" oddballs.
Another way would be to advocate for the addtion of Russian planes other than their top dogs. The Russians are missing huge numbers of aircraft, but of the top Russian fighters only the Yak-3 is missing. I-16, LaGG-3, MiG-1, Yak-1, Yak-7 and a huge variety of bombers.
