Clever idea... I wonder if you could do the same thing to "stabilize" or
"tune" a rotary gap, as well. The trigger pulse could be generated by
any of a variety of schemes (borrowed from an electronic flash, for
instance).

Would the heat in the gap melt the dielectric back, though? Since you
aren't concerned about impedance, what about using a ceramic insulator
(or something like plaster of paris or magnesium oxide, for that
matter).
