Ya thats kind of what we are using now, a "plug" type of device that resembles those "weatherpack" type of connectors you see on almost every north american automobile .. The nice thing about this setup is it disconnects hot AND neutral to the ballast. You are now safe from the hot conductor AND from having to mess with a neutral that may be part of a multi- wire circuit feeding other lights in the row, or from getting a belt off the neutral should there be something amiss elsewhere in the building's wiring.
