It's common with M42-to-E-mount adapters (in fact, all of mine have that capability), but I wouldn't have thought there was enough space on an EOS adapter to allow that kind of arrangement...

Maybe thinking T2 mount adapter?

Yes, that would make sense

Even with my OEM Pentax adapters on K-mount bodies the majority of my screwmount lenses align to about the 11 o'clock position. One or two line up at 12 o'clock. Just the vagaries of the adapters and lenses I would guess.

Ditto.

Some of the M42 adapters have the M42 thread on an insert ring that is held in position by 3 tiny set screws on the outside diameter. If so, just loosen the screws, rotate the threaded ring until the lens aligns correctly, and tighten the screws. Typically the set screws fit a V groove in the inner ring so doing this won’t affect the lens / sensor plane alignment.
