That question is a bit outside my salary grade.
The Germans were amazingly well advanced re swept wing aircraft towards the end of WWII - so I suppose it could have been possible.
The trouble with the experimental route to design is that it does tend to be a bit heavier than is possible later with a fully optimised maths based solution. The weight of the hinge assembly and the poor range of materials available to the Germans at that stage would also not have helped produce an efficient and reliable combat aircraft.

RIH popped up as I posted this. Seems to be some agreement there!
