I wouldn't go overpowering the element like that. Underpowering is fine,
because if anything failed catastrophically on account of the heater not
running hot enough, there would be problems whenever the heater gets
turned off. There's no such reason not to expect parts of the heater to
fail catastrophically due to overheating, if you go doubling the
voltage. Sure the curve starts to level off with a ceramic heater, but
that doesn't mean that it's level.
Cheers,
Kris
