You should not lose your license but the full scale pilot will likely lie and say he was above 500 feet and the FAA will believe him because he had an altimeter.
Let's not forget that every aerobatic contest breaks the 400 foot altitude limit as the box is about a thousand feet high. So we don't want limits outside of airports.
