Then, I know you said that triple blood is a thing for you, but in my opinion it should just be removed, it's stated in the Fe wiki that triple blood does not exist. but I let the choice up to you. If you choose for my idea then I would advice these changes :
Cedric: Remove minor Naga
Inanna: Remove minor loptyr
Hadrian: Remove major loptyr
Troy: Remove minor flayar
Parzival: Remove minor baldur
Cyrus: Remove minor baldur
Cynthia: Remove minor baldur
Rita: Remove minor flayar
Horace: Remove minor flayar
I don't know if I was too invasive or something but just something to bring up. Hope it helped.
