Sounds academic to me. You tend to have a Nikon or Canon body but not both.
Besides it's technically not possible - you cannot stop down Canon EF lenses on non EOS bodies.

I heard of a trick, but never tried it myself until now and it works at least on the 50mm f/1.8 II. It is to set the desired aperture on a body as normal and activate it with DoF preview. Keeping it down, disconnect the lens. Sure enough, the aperture remains set in place.
