With Heinkel too busy on other projects, in 1944 Junkers was charged with upgrading the surviving He-111 airframes.
Nice! One RW prototype - the He 111 V32 - was converted to annular radiators but that was with turbocharged DB 603Us to test the proposed He 111R-2 layout. AFAIK, your top image is pretty much what the abandoned,
Jumo-powered He 111R-1 would have looked like.
It all get even tastier when you introduce those Ju 388 elements

But, oddly, the Do 317 tails look best of all
