I would just be straightforward with your husband about how you feel and that you don’t want to saddle her with a difficult name. You don’t have to involve anyone else.
For names if you’re still thinking about alternatives: Maybe just Etta or Antoinette? I also think of Thea, Clementine, Hester, or Agatha.
EDIT: Just realized you already have Anthea, so nevermind Thea!
