A few ideas I had for the Hampden:
1:
Completely stripped version for Recce and other work that doesn't require armament.
Delete and fair over the spine and belly turret positions and create a system of pop-in mission specific modules to go in the weapons bay area. The idea would be that, when the aircraft got reassigned, the downtime would be minimised as the module could simply be switched and the aircraft could be on it's way again. A common attachment system would be built into the weapons bay area and all modules would work with it. All variants would keep a glased nose for missions where an extra crew member was needed.
Some module ideas:
Variety of modules with recce camera arrangements
High speed courier and transport module
Target tug module
Combination bomb pannier and gun packet module (Sort of like an earlier Canberra B.I.8 )
Torpedo modules in single or double recessed versions
Fuel module for long range ferrying
2:
Floatplane variant for rescue and recovery work.
Upper gun station could be deleted or converted to a spotter position and the lower station could be replaced with a ramp that could be lowered and used to slide bodies into the refitted weapons bay from the water.
3:
Widen the fuselage so it can have a proper co-pilot or one of the other crew members actually can get to the cockpit and keep flying the machine if the pilot is killed. After that, give the plane back to Bomber Command.
