Would be pretty cool to see a 109 variant that was actually flown in significant numbers during the portrayed timeframe.
I.e. G6, G14, G10.
IMO the smartest move would be to release a BF109 G module with a baseline 1944 G6, so a version with a DB605A, MG131 and MG151/20, Erlaa Haube, Galland Panzer and the taller vertical stabiliser as standard,
with options to add MG151/20 Gondolas, the MK108, DB605AM, DB605 AS with corresponding engine cowling, DB605 ASM with corresponding engine cowling and DB605DB/DC engine with the corresponding larger oil cooler and engine cowling.
This would enable us to fly a wide variety of historically accurate scenarios over a wide timeframe, as the G6 was the baseline for basically any subsequent non-K 109 variant.
It could serve as the G6, G6/AS, G14, G14/AS and G10.
