No, for a very good reason - the camera doesn't work that way. It doesn't really matter what aperture you set on the lens. Not only does the camera meter at full aperture (as you know) - it will also expose at full aperture, without stopping down to your selected aperture (it does seem to briefly stop the lens down at one point, but this is after the exposure has been made).
