No, I wouldn't use
Lewis for a girl. But I guess since
Lewis is a placename, it could sound unisex theoretically. The Isle of
Lewis has a different etymology than
Louis, at least.
The names themselves are ok. I pronounce
Louis as loo-ee (or lwee? seems nearly the same to me) normally too. I had a uncle named
Louis.
Lewis seems a little more surnamey to me than
Louis.
