To answer your question, there are currently no official Vocaloids with the name Amane, Muzai, or Amane Muzai. I can't say the same for other characters/UTAUs, though.

Amane is a fairly used name. I honestly think it's alright if you use the name of Amane. But Muzai on the other hand is not as used so much as a name. (I would actually recommend spelling out Muzai in katakana rather than kanji...? But that's just my recommendation.)

But like Dizzyzebra said, it's more like an Vocaloid oc that you're trying to make to represent yourself, which I think is perfectly fine. But if you use the term of "Vocaloid", that might confuse people a bit. Perhaps you could use the term Humanloid, or even better, an utaite. Both types of singers usually utilize some sort of avatar. While utaites generally do a lot of cover songs, a lot of them also sing original songs of their own, so that might be a good fit for you.
