No. Like TW said if that had been proposed, you would have heard about already on APC and every other board. Maybe some congress-person mentioned it in passing?
Don't worry though, while congress might have their way willy-nilly with professional pilots, all of the doctors, lawyers, and businessmen over at AOPA would not sit still for this for one instant. AOPA is usually pretty effective when they get riled up.
Some (most) airlines have a 12 hour rule (not mine ha,ha) that can get you fired, but probably not violated by the FAA.
