If I may. Actually, it's not a stupid question. The answer is > it was tried. The result was less or same power due (it is believed) to be the nature of how a plat or iridium plug 'creates' the flame kernel (i cannot recall all the detail. sorry). the key is the electrode size, and is the reason they have to use rare earths (heat and wear). There is a vid on the net (somewhere) using a highspeed camera that shows the diffs. I have no idea where it is though anymore.
This is an area with a lot of conjecture. If you find the vid, watch and make your own conclusions.
