Why is it that it bothers you that it's a Greek name and not that there's a planet named after the sky?
The main reasons to rename Uranus is 1) consistency and 2) the puns. Either name it Caelus to be consistent with the naming convention used for the other planets or name it Ouranos to be closer to its Greek spelling and pronunciation.
I prefer (1) because the current situation is similar to having a codebase where all class names are PascalCase but there's this one class name in Upper_Snake_Case.
That's a reason to keep the name - it's a rich seam that never seems to run dry. Also, if we did want to change the name, we all know what the anointed successor is...
It is the woman, primal mother.
Her gateway is the root of heaven and earth.
It is like a veil barely seen.
Use it; it will never fail.
~Lao Tzu
