+1 for the 177 
copy-pasted from an earlier side-by-side comparison of the He 111 and He 177 I made a while back...
Heinkel 177:

Crew: 5
Range: ~3400
Wingspan: 103ft.
Range:
Bombload: ~13k to ~15K lbs.
Defensive armament:
1 × 7.92 mm MG 81 machine gun in nose position
1 × 20 mm MG 151 cannon in forward ventral position
2 × 7.92 mm MG 81 machine guns in rear ventral position
2 × 13 mm MG 131 machine guns in FDL 131Z remotely-operated forward dorsal turret, full 360º field of rotation
1 × 13 mm MG 131 machine gun in manned aft dorsal position
1 × 20 mm MG 151 cannon in tail position
And she's got the ugliest profile you ever saw

Not sure how the remote gun would work. Perhaps like the 5" guns currently do, a shot of the gun and a red +?
The dorsal gun, note the glass dome from which the gunner would control the weapon:

Ventral cabin of the bomber, where the controls of the remote guns are located (2):

Made my post nice 'n' picture rich for those of you with short attention spans.
