At least the color drawings that you posted are What-If material. When Logan was making these, I was sort of hoping that he would do a Heinkel He 100 with a DB 605 engine....
It was one of those ideas whose advantages were obvious and whose disadvantages less obvious. Once the He 177 was in production, there was no real alternative that didn' involve major modifications (and unacceptable delays). Not enough time to do it right, but plently of time to make never ending series of minor changes that, while overcoming some of the problems, never provided a fully satisfactory result. Then the DB "Power System" engines were even adopted for the Ju 288.
