Is it theoretically possible to create an aircraft like this? I was browsing through some funny airplane pictures when I came across this. An airplane with the engines replaced with the cockpit and the cockpit replaced with a huge turbofan.

I was intrigued by this idea, but then it also brought up the question: Is it theoretically possible to create an aircraft like this and be possible for the aircraft to take flight? (as in fly in the air for prolonged time)

The idea has been tried. This WWII aircraft is built around the idea very much like yours: engine in the main fuselage, pilots/passengers in the nacelle. 

It must be reasons to choose this design. The design requirements were:


One engine.
Crew one or two 
Best possible view into to all sides
(reconnaissance aircraft).


For the passenger aircraft as pictured it is probably just not optimal.
