Camazotz (https://en.wikipedia.org/wiki/Camazotz) would be great, because of the Wrinkle in Time association (and it means "death bat"), but the IAU standards (https://www.iau.org/public/themes/naming/) don't actually cover new major planets (just minor planets)...
I kind of want it to stay in the Roman pantheon, but all the names have either become jokes or already belong to asteroids. Maybe Nox would be cool, if that isn't taken. Or, perhaps we could build some sort of weapon to vaporize all the insignificant little name-hogging floaty rocks, to free up some Roman goddess names.
(I guess I should add, I also like Camazotz; it just seems like it should be in a different solar system, with all Mayan names. My OCD is showing, I know.)
FWIW, we have dwarf planets named Sedna, Haumea, and Makemake (well, Sedna's not a dwarf planet, it's a "Detached object" TNO, but it's the size of Ceres)... I think that most of the big names in Greek or Roman myth have been taken...
I seem to remember someone from the IAU saying that it would probably end up being a Greco-Roman name, but the only quote I could find today was less definite:
