The only things I can find about banshee appearance is they either appear as an old hag or beautiful young women, with a white or grey hooded cloak, have pale or red hair, and are said to be seen using a silver comb in their hair.

Barring the cloak, Lydia fits the bill pretty perfectly as is. Whole we don't see her using combs or brushes, she clearly does frequently as her hair is normally perfectly coiffed. And I'm almost positive the brush we saw her mom using on her back in s2 was silver.
