Although Xavier is okay, this feminization doesn't look very attractive. It's not ugly though, just a little strange. Rarely any girls nowadays are called Xaviera!
It's certainly unusual and not very common. It looks pretty though there's many pronunciations for this name, so you'd probably have to correct people all the time which can be annoying.

I think it's gorgeous, actually. I say it Zay-vee-AIR-uh. Elegant and strong and kind of exotic.
