A-26 stuff...
You missed my point. The A-26 is not much faster than the A-20G (it will not keep up with the fighters as you say) but carries a lot more bombs and guns, enough to where it will be perked, though I would guess it would be the cheapest of perk bombers. Those who want to use it as a fighter and concentrate on the number of .50s it has will find it annoyingly perked, and ganged as a perk plane, for no gain in firepower over the two heavy fighters I mentioned and their lower bombloads are irrelevant to that. Some will still fly it for the challenge of using it as a fighter, but it will not be nearly as common as you seem to think based on advocating it over a "hanger queen". The A-26 will be a hanger queen for the same reason the Spitfire Mk XIV is, not enough bang for the perk cost.
No Ta-152? Or did that get thrown in under all the 190s and Focke Wulfs? I'd at least consider it two different airframes still, between the A series and the long-nosed Doras and 152s.
The Ta152 was only not the Fw190E (or whatever letter) for political reasons. It is obviously a continuation of the evolution of the Fw190 series just as the Spitfire F.21 is a continuation of the Spitfire line despite completely redesigned wings.
