Talking about that, you missed sun! And as talk, there's no mentioned about if Stella has any other sister(s), even twin or not, but then that twin should have appeared when king Radius had been in big trouble in "The Pillar of Light". By that point of view, it's just your theory. There's no way a daughter left her father living dead and just enjoyed her life!
