Also Artik,
IMO think the 109G wouldn't be the best choice for the AVIA S199. Way too capable an airframe to sub for the S199.
The Mercedes engine being replaced by the Jumo 004 (used in the HE 111 bomber) really cut down on the power and made it a difficult if not dangerous a/c to fly. They didn't call it "Mule" for nothing! Was thinking of more along the lines of the 109E.
Also the TBM is a "little" ubber for a AT-6 Harvard IMO. Think the VAL is pretty close - SBD would be good also if it didn't carry so much bomb load. I just don't see a AT-6 picking up a 1000 pdr and 2x 100 pdrs.
I do like your set-up listed above. Maybe some time in the future, when the whinners have calmed down and when they have the bugs out of the mid east map we can do something in this era again.
Myself, I am still trying to figure out how I can replicate barreling down the Bakka Valley in my trusty F-4E Phantom II hunting SAMS.
