remind me never to play a Tabletop RPG with you, munchkin.
Seriously, we don't know much about how Nicrosil works yet (although the second Mistborn trilogy will star a Nicroburst apparently). So I don't know if that wold work or not.
Although Brandon said that there are going to be very few Mistborn in the future of the setting due to dilution of allomantic potential, so that probably won't ever happen in setting, even if it's possible.
