Thanks for the info Sagallacci.
So no measures/angles on the short nose type and the alternate wings or even a drawing?
As for the twin V-1, I agree with your statement. The speedincrease wouldn't have been siginificant, only the payload or if they chose to increase the fuel amount instead of a second warhead i.e. the increased range (which would have been the only reasonable pro considering the lost or soon loosing of areas as starting points in reach of targets in Britain).
And although the building of a twin V-1 could have used most of the existing parts of the missile, all the ramps and starting mechanisms would have had to be adapted to this new types as well, which was probably a far more complicated matter than bashing the twin V-1 together itself.
