Been there, done that.

It forms carbon tracks on the G-10 and eventually starts burning.  Didn't
work well at all.  The electrode material, as it burns away, forms metallic
deposits on the insulation and then the gap gets erractic by firing to the
plated metallic deposits instead of electrode to electrode.

Good idea, but as they say, there's theory, then there's practice.
