For starters you'd need ejection seat technology to move up quite a bit lest the rear props do so nasty things to bailing out pilots.At work.
Am quite enjoying the thread.
Much interesting information and points of views being presented.
Just a question. Given the OP's comment of kickjng things off in 1936......
What sort of butterflies might be needed for something like the Do 335 to be thought of and/or developed?
Or is four years not enough time?
Cheers.
The below is from the book "Dornier Do 335 'Pfiel'" by Heinze Nowarra.
The genesis of the Do335 goes back to the Do18 flying boat with tandem engine layout, which was a 1936 design and in 1937 he patented the concept that led to the Do335 and started working on the technology. When he proposed it as feasible in 1940 the concept was rejected by the RLM, but Dornier still built a proof of concept aircraft, the Gö-9. Apparently once that was fully tested Dornier worked on a family of aircraft with the tandem engine layout, which was ultimately cancelled in 1943, but replaced with spec for what became the Do335 and the work was folded into that project and got Hitler's endorsement to make it a priority project, which yielded the first prototype for testing in late 1943 (October or so).
For a realistic POD Dornier would have develop the technology sooner and get the RLM interested in funding it as a high priority project, but given the engineering challenges, I don't really see how it could be ready before 1943 even as a high priority project as of say 1939 when the proof of concept was started. Short of ASB there is no way to even start the project in 1936 due to all the basic research that needed to be done first to even demonstrate the idea was workable for a military aircraft.
