I think that running the oil lower than where the level would be if using a standard depth pan helps reduce windage, as you said. This is of greater benefit than running additional oil in the pan, IMO.

What would be the noticeable effects of running the oil level too high be ?? Would the oil splashed splashed on the cylinder walls due to windage over power the rings causing oil consumption to a point until the oil was at a level below the crank that would not be effected by windage ?
It could very well overpower the oil control rings as you stated. You would likely lower the level yourself before waiting for the oil to be used up by burning it, though. There would be a lot of noticeable smoke, and the plugs might foul, the engine could well be detonating because of the oil diluting the incoming fuel/air charge, etc.
