I'm afraid you're ignorant of the issues, tank-ace. And calling me an idiot doesn't change that.
No, a G-10 would not be a good idea, because what you THINK of as a G-10 is not what you'd get. What you want and what you are calling a G-10 would much more closely resemble a G-6/AS, and this would also fill a large planeset hole in the game that ranges from 1943 until the beginning of 1945.
I have no doubt if we got this G-6/AS, many folks like yourselves would fly it exclusively amongst 109 variants. All the weapons options of a G-6 (including 30mm), the high-alt supercharger of a K-4, and in service years before a "real" G-10.
