Increase 190A5 ata from 1.43 to 1.49 to represent the majority of A-5 models.
Add bombs to the 190F-8, which requires no new visualizations to be created, and simply requires adding the existing ETC 503 bomb rack onto the wings and enabling 2 250kg bombs on the wings, add the 1000kg bomb to the center line.
Remove 800lbs of weight from the A8, as most models did not have the added armor (and armor seems not to be modeled in AH anyway)
All easy fixes providing actual performance differences than your D-23, and making the model more representative of history.
On top of that, there's also the gaping holes in the German bomber set, our sorely needed G-6 or G-14/As, the Ki-44, Italian SM-79, the H8K, the Beaufighter, the Yak-1, and Lagg-3, Seafire III, the Vickers Wellington, Pe-2. All would add far far more than D-23 would to the game, and all deserve a much higher spot on the priority list, given that the D-23's performance can be not only approximated, but PERFECTLY MATCHED by the D-25.
