Those look pretty good. Definitely looks space-born. Surprisingly, Latin and Spanish are not hard to pronounce. Tempus as TechPr1est suggests is pronounced like temp in temperature and us. The thing with Spanish is that the vowels only have one sound, unlike English, so that makes things a little easier and there are virtually no silent letters. But if you aren't comfortable using the language then you probably should not. Look to mythilogical beasts like most of the GW fleets have. Hydra, Basilisk, Gorgon, Revenant, Cerberus, Dryad, Golem, Naga and Syren to name a few.
