Allow me to be skeptic. For all ita unique design, the F.23 was only powered by two 530hp engines. That makes for a total of 1060hp, less then one Rolls Royce Merlin or one DB. If Fokker would have access to one of these engines, I'm sure he'd ditch the pusher-puller configuration in a heartbeat and go with something more conventional. For all its fancy features the plane was more of an exercise in making do with what puny resources they had available.
And for the question of what would happen if Fokker would have been able to produce the F23 in series before the German invasion: Again I am sceptic, but now for another reason. Right up to the invasion, the Netherlands were trusting their neutrality and were not really in a hurry to spend new money on new planes. France, and in lesser extend Belgium were buying every plane they could get their hands on. So my guess is that all F23's Fokker would be making would.eventually be flying with French, Belgian, Norwegian, Finish or even Romanian cockades.
