Where does this sort of thing end? Seventeen D-13s and two saw limited action? How many other fighters and bombers would this push onto the table?

The Ta152H-1 left the door open for everything.
Btw, you say it was easy to add because of the D9... you cite the cockpit and tail as being the same... I've been looking that over.
The cockpit and tail a plane don't make and the rest of the differences are many... 7' longer wing span and different shapes, 2.5' longer body, the vertical tail is larger area, the cockpit <inside> are not identical, forward fuselage hump is gone and is longer and narrower ...... The cockpit <complete> is moved back 2 feet. The horizontal tail is the same shape and size ...but made of metal instead of wood.
That dose not leave much unchanged. Shall I get out the drawings to illustrate for you?
All your blither about it being "so easy to add" is a Bunch of Dr. BS Karnak in radioactive dream state. I'm sure it is more like Saxman says and is a whole new and different plane on the 3d mesh.
