'm trying to work out if you're playing devil's advocate, or blissfully ignorant.
No, neither.
The original premise was whether a 24 hour break should be required between switching cockpits. Respectfully, I don't see any justification for this at all.
Adapting to the different control inputs required on different types happens as soon as flight begins.
I agree that lack of familiarity with a different type may lead to a spot of initial finger trouble with instrumentation and switches, but I don't think a 24 hour break would help with this at all.
