I really love Nimueh and in my opinion she will always be the one and only High Priestess. I'd like to see her again, but I also see no way in which she could return, without making the series stupid and banal. There could only be one way: going back to show what had happened before/during the Great Purge (if there'll ever be a Merlin movie, that's what it should all be about) and so returning to Nimueh's story and the lifes of the High Priestesses before the destruction of the Isle of the Blessed (maybe with Elaine like you suggested). As for Morgause, during Series 4 I was really hoping she would come back, maybe as a ghost and see her once more with Morgana. But I've finally realised that her story is finished: without Uther and with the beginning of Arthur and Gwen's kingdom, she belongs to a past era (the one of Uther's villains and not Arthur's). So I've accepted the fact that I won't be seeing Nimueh and Morgause again.
