I vote yes, it could create an interesting dynamic. And I have seen it in other books and movies before. Born vampires vs turned vampires, could give an interesting twist as to why Leiha is already a council member. Her skills are unmatchable in what she does and she is a vital part of keeping stuff going in the modern day. But her age is clearly a con for her, but say she is from a born or pure blood line. That would explain why she is council member while Angel is still a shade despite her power and age.
