I believe a better analogy is trying to warm your Cofee pot uniformly with a 3700 C capable hydrogen blowtorch without melting it. And just to aggravate things the metal pot tends toward nuclear meltown if Rydberg conditions are just right, which happens to be right where you want to operate...
The advantage I see in using tungsten spark plugs is the higher melting point of tungsten at 3400 C might have you buying less spark plugs.
