How to change a creature's name (Change "Hexxat" to "Clara")- Hexxat Spoilers

Hello all,
So while making our Mazzy mod we ran into Hexxat. Mazzy hates Hexxat so when she sees Hexxat kill Human Hexxat (Clara) she wants to kill Hexxat and get Clara raised again. The PC can choose who he's going to side with, but if he picks Mazzy and Hexxat dies (maybe with some extra dialogues to stake her in her coffin in her little bag) then human Hexxat (Clara) rejoins your party.

Except that I don't want the old file for her (OHHFAK) to rejoin your party, I want a new creature named "Clara" to rejoin your party dead because I don't want all the old sound files, interjections, etc. attached. The easiest way to create Clara was to take a Human Hexxat file (OHHFAK.cre) and copy it and then edit it, and then add new dialogue and script files. I know how to create the files (and there's plenty of guides) and editing everything is easy in Near Infinity except for the name (it looks like I can even make her start dead). The creature's name (Hexxat) is a string reference: String 84186. How do I change it to Clara?

Thanks
