If we're going to do the 190's, we could do with some expansion of the set along with it. Right now it's kind of a grab bag of prominent but not particularly representative models.
An Fw 190A4 would make a fair representation of the A2-early lower-boosted A5's. It was a fairly major variant in itself, wouldn't be ungodly fast vs the A1 and A2's, nor drastically heavier, but would keep most of the armament and performance characteristics of the early A5's.
And then we could get a later 1.65ata boosted A5, or perhaps an outright A6 to fill up until our bomber-buster variant of the A8 goes into service.
