That's fine for 1946 but the He-177B was proposed during 1938.

Instead of using a push-pull arrangement, tandem engines driving contr-props could have been achieved.
Like the Ki-64, except that the engines would be closer together.
http://www.ww2aircraft.net/forum/album/aircraft-cutaways/p18647-kawasaki-ki-64.html
Both engines could operate separately, and one could be shut down for a slow cruise on a long range mission.
Somehow Roy Chadwick, Ernest Hives and someone at the Air Ministy managed to get the Machester/Vulture issue resolved by creating the Lancaster/Merlin combo. The catapult launched and slide bombing Manchester was almost as silly as the 45-60 degree dive bombing He 177 yet the British muddled their way out of the mess by pulling the plug on a troublesome design before too much effort was wasted on it. Maybe the difference was that the Vulture was seen as an completely new engine while the DB606 was seen as simply two existing and established DB601's coupled (I mean what could go wrong?)
That was also true of the DB coupled engines.
It seems that there's nothing inherent in a coupled arrangement that can't be worked out (a lot of the Heinkel's issues were with what some might think fairly straight-forward things like the routing of oil lines, fuel feeds and so on - not forgetting the lack of firewall) but the concept wasn't all bad, I would suggest it was largely the implementation of it that was the problem as much as anything.
The dive bombing requirement obviously hurt the design and caused great delays (and still according to some reports the wing was not as strong as it ought to have been for level loaded flight!) but there are records of Goring specifically saying, in Sept 1942, that the diving idea was stupid not needed if the plane was being delayed because of work to make it dive then the idea should be dropped straight away and the plane operated as a normal level heavy bomber.
That's fine for 1946 but the He-177B was proposed during 1938.
Slide bombing? What is that?

I hate to see every failure get blamed on Hitler. Let's not forget Goerings statement " The Furher doesn't ask me how big my bombers are, he ask how many bombers I have" That's paraphrased, and from Goering, who knows if it's really true, but if it is the lack of the heavy bombers being developed is the way Hitler wanted it.
The efficacy of the push pull arrangment was well established by the Dornier flying boats by 1938 and the configuration had been explored in some Heinkel flying boats as well. Google the configuration and you will get lots of opinions and some maths about how the rear prop looses efficiency.
Reality however is that one of the fastest prop aircraft of the war (possibly the fastest) the Do 335 used this arrangment, while the Dornier Do 26K was one of the longest ranged aircraft ever built. Theory and opinions aside: the arrangment worked very well in practice!

I agree ... his tea time chats with Eva and the secretaries are the "real" Hitler .... chatty, gossipy, trivial, boring beyond belief. The softer, gentler, sensitive artist {wantabe}. He didn't smoke, drink or eat flesh ...... just the kind of bright spark you want at your Super Bowl soiree. [I hope the mods don't think I'm veering towards political)

The four engine Ju-290 had an even greater range / payload. Otherwise Do-26k would have been making the trip between German controlled Crimea and Japanese controlled Manchuria.Was the Dornier Do 26K (?) one of the longest ranged aircraft ever built (that in itself is debatable) because of the tandem engines or in spite of the tandem engines?

It's possible to see Hitler as an inner city emo doing inner city radical politics, even has the hair flick.
