Some one is going to come back and say "hey I've done that for years and it didn't hurt anything" well depending on the environment the car is in if the ratings of both oils work great in those conditions of course it won't matter. Put it in an environment where one of those ratings has that oil too thick or thin and it's going to be another story. This isn't mixing differing octanes here.

You don't solve a pickup problem with an oil's rating, you solve it with some kind of sump or baffling around the pickup. This of course also ignores the fact that if this worked how you expected it to work and the "heavier" oil was around the pickup what happens when that heavier oil makes its way to the head or the cams?
