I have a Lucia (pronounced Loocheea). Sometimes people say 'Lydia?' When I say it.. Nice name but not quite.. Anyhow, I don't really mind Luseea, sometimes even prefer it! Depends how particular you are. I have had lots of compliments on her name.
Not keen on your other names.. Both quite popular here, and Emilia, Amelia... Which one? I have said the wrong one to a friend who has an Emilia. Easily done.
