The basic 6 made a hell of a lot of sense, easier to adapt to as a pilot and a damn sight cheaper and faster to make. While the Brit bombers were designed for a single pilot it wasn't unknown for another member of the aircrew to know how to fly the bus even though not a full pilot so they had some backup if the driver got hurt.
I used to know a Polish pilot (worked with his son) who started off flying Hurricanes and ended the war in Mustangs then stayed in the RAF and finally retired when Lightnings were all the rage.
He said converting between the types was trivial for experienced pilots, no more tricky than jumping into an unfamiliar car, although he did say it had some risks. One of his younger mates on his first Mustang flight decided it was a great idea to throw the throttles wide open, rather than easing them up, while still close to the ground and the torque slammed it into the nearest hillside.
I'm not in the slightest bit surprised by the Tedder memoir, in those days innovation was encouraged and the build time for a prototype was pretty short, ironing out the kinks took some time, but clearly the Lancaster didn't have a lot of those.
