Yes a direct hit should vaporize a spark plug. For a 100 kA hit two 1" diameter rounded steel balls may survive.
Note that Ross Engineering uses carbon balls on their spark gaps. At 50 kA/us every inch of wire will have a voltage drop of 500 to 1000 volts, so very short wires are in order. Wide copper straps having a length-to-width ratio of 5:1 are good.
