Morgana has been explicitly denied by Kat; Morgan was mentioned in the ask where she said her name wasn't based on a pre-existing character, so while she didn't explicitly deny that one, it was heavily implied. Evanna has also been denied.

I suspect we will not be able to guess her name since Kat believes that it is completely meaningless (no connections to her color or a known fictional character). If it is somehow related to either of those, it's likely something very few people know about, further suggesting that we won't be able to predict anything.
