Enigmantis

A couple of people have questioned what, if any, abilities Nightblood might give to Szeth. People were mentioning that it may be a combination of surges different to the combinations any of the orders have. Noone seems to have mentioned that, since we know metals foreign to Scadrial once taken there can bestow investiture orther than what is already known from the planet (i.e. Paalm's spike), is it not possilbe that Nightblood will give Szeth surges different from the other ten known ones (as the spren is foreign to Roshar)?
