To build a Ta152E-2, would it be sufficient to rescribe the panel lines of a Ta152H for the large hatch, giving access to cameras, create the windows for the cameras, and 'build' the aiming device for the pilot?

Any reference I have, states an E-2 was based on a Ta152C fuselage with the Ta152H wing and the Ta152H Jumo engine, but I can't believe the Ta152H and Ta152C fuselages were different beyond engines, wings and armament or the production lines would have been 'royally congested!!
