It'd be nice theoretically, but it does nothing for me.
Harmony Rose is too word namey for my tastes.
Harmony Jean's nice in theory, but I think of
Hermione Granger (
Jean's her MN), and... well,
Hermione is one half of the aforementioned 'ship.
Then again, I doubt this would really be an issue for a real
Harmony Jean, so I'll get over my reservations and say that it works. Sorry, I'm really bad at coming up with other MN possibilities, but I agree with you that
Harmony needs something simpler and less frilly (hence why I like
Jean) to balance it out.
