I'd love to see Tasha (or Iggwilv) the adopted daughter of Baba Yaga and author of the spell Tasha's Hideous Laughter (among others) in Dungeons and Dragons. She recently got her own sourcebook for D&D.
Sounds like some cool lore behind this character. And it would be interesting to make a pattern of a pretty witch. Although... "some described her as a ravishing beauty, while others claimed she was a bald and hideous crone."
