It's ok, but
Lucyna is pretty old-fashioned and I've never liked
Dorota. I don't know if
Lucyna is far enough from its last peak to come back yet but I think it can be really endearing. She could go by Lucynka or Lusia, or Luśka for a more playful vibe and those are super cute, but I don't know what a suitable nn for an adult
Lucyna could be and the full name sounds kinda heavy and clunky to me.
