Fact is that a tank busting version of the mighty Ju-88 was produced it had a 50mm PaK inserted into the solid nose, and another version i think had a 75mm PaK in a ventral gondola and both were exceptionally deadly, the method was to sight the PaK with a short burst of cannon fire and then shoot of a round at the armoured vehicle.

The Ju-87 had two 37mm Pak under each wing and were used in good effect against armoured cars and trucks, locomotives and light tanks but not good against later Soviet models.

But to answer this question by T. A. Gardner If i was in charge Germany i would decide to scrap all production of the He-111 and Do-17 family, i would continue production of the Ju-88 as night fighter and ground attack aircraft, i would continue with the Ju-87 as ground attack and anti-tank, then i would continue the production of the Me-109 and Fw-190 families as dedicated interceptors, fast track the Me-262 as a pure interceptor.

If this could be achieved i would have at least tripple of the amount of fighters in service to intercept allied aircraft.
