Were the Lancaster and the other heavy bombers over-manned. The crew of seven was pilot, navigator, flight engineer, bomb aimer, radio operator, mid upper gunner and rear gunner. The Mosquito made do with a pilot and navigator. Could the mid upper turret have been dispensed with? It would have improved aerodynamics. Could the navigator role be combined with the bomb aimer? Did they really need a flight engineer? Did the radio operator only operate the radio or did he operate other electronic equipment. I'd have tried to reduce the crew to four.
