Here's a link to a pdf from the RPG game I found that has a bunch of sample twinborn name combinations about 3/4 of the way down, if that's helpful.

I'm a big fan of the cosmere and its lore, but I've only read stormlight archives/mistborn and I've yet to read the Bands Of Mourning. 

I'll start working on a character.

EDIT: Feel like we could do with more info on the RP premise for character creation. should we be lawmen or criminals? are we going to be in Elendel or out in the Roughs? that kind of thing.
