The problem I can see with this, if you will forgive me, is if you allow almost every German Prototype, let alone drawing board idea, to become a real weapons system, then you have to do more or less the same for other nations too, or you are giving the Germans an advantage they never actually had or could have had.

In reality US, British-Commonwealth and Soviet Russian weapon development all slowed down from about Spring 1945, since Japan never could have held out all that long after the fall of Germany, with, or even without, an US/allied 'A' Bomb.

So to do this, with any realism, you also need to look at Allied paper projects or, at least Prototypes, and turn the best of them into real weapons...
