I don't think they'd be interesting rp avenues, outside of events maybe.
I don't think the op races should be weakened just to be playable.
Nor do I think dullahans and liches really add much to Korvara.
Vampires maybe add a bit, but the way they'd work lore wise would have to be explicitly stated.

And its a big pandora's box i'd just love to not see opened for a very long time.
