I like try to fly the Learche with on engine off the same engines prop feathered, so funny, can almost land it too on one, if you don't mind getting a bit dizzy or nearly cooking the remaining motor.
Sos' for the off topic-ness.
Battle damage on the 215.03 with holes on wings near the tips, or damaged on the tips should cause those to suffer some tip control(s) flutter/buffet, as this is sort of what the DVL/RLM were worried most about with this family of design.
While radio controlled models do not recreate the specific structural wieghtings and equipment loadings etc, they do provide a good basic ball-park representation of some characteristics, many plane designers used to make designs into hand throwable balsa and tissue models, to test throw/glide before windtunnels were built, or devoloped/proved enough to get access to windtunnels.
People still do this when designing there own RC plane design, by making a simpler 'free flight' model to evolve upon.
The fact that some of the drawings for this family of A/C did include systems & equipment or space for 'being developed' equipment, means that paperwise, things are quite far along, say around 20% of the way to the 1st prototype being started.
Having said that, this would more likely be like the DH spider Crab or Meteor, entering during the end of the war. They came close to pulling off something devastingly unforseen, and caught the allies 'with their trousers down' a few times - just as we did to each other, them and others elsewhere.
