Now why would you want to net your receiver to your own
transmitter, which might be mistuned from the other transmitters
in the flight by a Kc or 2 or even more? Wouldn't that result in
the entire flight's receivers being mistuned all over the spectrum?

Isn't it more likely that the pre-flight check required each pilot to
switch to CW and use his BFO to zero-beat his receiver with
the flight commander's or control tower's transmitter?

Was the pre-flight check the entire justification for the receivers'
coffee-grinder tuning, or was it necessary that the pilots make
large changes in receiver tuning during missions when they would
receive orders to do so for tactical reasons?
