Hey, if you want, I can probably come up with a few hundred different names for your Hero units based on Game Race, and even based on unit type (Archons would all be "XX/YY" names, SCV names would be more pedestrian than Ghosts, Battlecruisers could have ship names instead of human ones, Zerg Queens more regalish Zerg names than zerglings, etc.)

Pool em together with any that you or your friends that are bored can come up with, you could probably get a few good sized CSV filess to query from. Maybe add weights to the CSV files so a Battlecruiser has a 95% chance to pull from a certain one with more aristocrat names, but still a 5% chance to get a pedestrian name, etc.
