My daughter's name is not a made up word, but it's not usually used as a name. We are shameless old hippies and it suits our family and more importantly her. It is a beautiful name and she can carry it off, and if she decides to change it that will be absolutely fine. Lots of cultures have individuals change names at various points in their lives.
I, on the other hand, am called something like Emma or Sara. I find it a pain to have to explain who I am all the time. Everyone knows at least twelvty thousand people with my name so whenever I phone anyone I have to be "Emma, DH's wife" or "Emma, DD's mum" or "Emma, X's secretary" even when speaking to people I call all the time. I am "Emma, DH's wife" when I call my inlaws fgs!
DD, on the other hand will be "Hello, it's Magenta-Pythonella here" and EVERYONE will know who they are talking to .
