[Opinions] It's too strongly associated with a celeb, sort of like Beyoncé or Madonna (the combo) and also Sailor Moon, so no, not a fan (more)
1) I would hate to share a name so strongly associated with a celeb because if she does something stupid (drunk drive, hate on people etc.) it becomes part of the name. Same with Beyoncé,
Madonna,
Elvis or Trump.
Soleil is not too strongly associated with her but
Soleil Moon is.
2) Sailor Moon. It sounds like Sailor Moon).
3) "sun moon" is a stupid meaning.
4) I do like
Soleil and Moon is ok, but not together.
