That's really likely. It also goes to show, Kilgharrah wanted Morgana dead (initially refusing to give Merlin the power to save her), and that was his way of stopping the future happening.. he didn't, though. Aithusa on the other hand, may think differently from Kilgharrah. The white may represent the contrast between them. Aithusa is brought Morgana back because he knew a possible good could come out of her one day, and that is, her saving Arthur in the end and encouraging him to bring magic back to Camelot! We'll have to wait and see.
