since we're talking wish list, I'd like to see a perked version of the 190D. The D-11 was very similar to the D-9 - with the notable addition of two 30mm cannon in the wings, outboard of the existing 20's.
Also, what about Night Ops? I'd call it a new frontier for AHII. Think of the possible add'l a/c: HE219, P-61, JU 388, etc.
Also, why no Me 210/410? Historical accounts show them to be numerous and reasonably successful bomber hunters, if kill-pads for the Allied fighter jocks.
