I am pretty sure if it was that simple it would have been done that way already. Breaking high currents is something we had to do for more than a hundred years.
Arc flashes are no joke. We are talking about 2800 to 19000 degrees Celsius here. I don't know about your insulator but it has to survive a multiple of the surface temperature of the sun. And ideally it withstands that more than once or twice.
