Parts getting use to running with a thinner gap than is required with dino lubricants, where dino runs at a larger gap.

hmmm...so you're saying that your oil can determine how far apart the metal parts in your engine operate from one another and that synth oil puts a "thinner" coating on metal parts than dino oil does? I always thought that the tolerances in your motor are what they are,minus wear ofcourse,and your oil can't affect that other than by allowing wear. For the most part,internal components are surrounded by oil,so the gap is always going to be the same no matter what you run. How can you increase the gap on one side of a part without reducing the gap on the other side? Unless you are stating that dino oil "compresses" parts,making them smaller,thus allowing for a larger gap all the way around.

Anyway,I've checked a couple of other websites and they all state in their faqs that it's ok to run/mix synth with conventional oil and to change back and forth at will.
