I am not trying to be argumentative, but I fail to see the logic in turning on a cold engine and drawing up oil out of the pan, versus just draining when cold so the maximum amount of oil is already sitting in the pan.
With modern synthetics, I don't feel that it would be advantageous to put a "coating" on key engine components like what you are describing. It's not going to be running "dry" at first startup after oil change because there's always a thin film/coating and you're never going to be able to get all the oil out of the motor even if you let it drip for 6 hours or overnight.
Perhaps a better method for not "running dry" upon first startup after oil change would be to prime the oil filter with a half quart or so so that there's already oil in there for the motor to draw from versus an empty filter.
