Outside of silly, your proposition also allows to encode more information into the name. Race could be geographical origin, class can be if it's state-sponsored or independant, level the "level of danger", and gear the methods used. You can even add an actual name to easily refer to them. But the issue is that in both of your examples the coded descriptions aren't really shorter than the real descriptions. I guess this is the issue, they want names that are a bit descriptive but not a full description, and you gave a full description. Still, I agree that half silly is the worst (at least to me), it sounds like "corporate-allowed fun" which ruins the point.
