Regulators principles

What about Estinien's case ?
He was possessed by Nidhogg, and during the final fight in 3.3, Nidhogg could take a hybrid form with mostly Estinien body in appearance, and his wings.
Since then, Estinien can call forth Nidhogg's power (I think it is the case ?).
Besides, did Nidhogg's remaining Aether fuse with Estinien's when he bathed in his blood and been possessed such a long time (maybe it enhanced his strength above what he could have achieved alone without that power/possession or bathing in Nidhogg's blood) ?
Could he take a hybrid form similar to the Arcadion's fighters if he wanted to ?

I think that sounds believable there are myths about bathing in dragons blood and gaining power and while he should be able to transform transformation like that is reserved for the enemy.

It's more drinking dragon's blood. We've seen several times in the MSQ and side stories about Ishgardians who drank the blood and transformed into various types of scalekin/dragons. There's a quest series in the Firmament about a guy who turned into one and couldn't turn back.

I was more referring to the irl myths of dragon slayers besides between those that drank dragon blood and the one guy who bathed in it who came out ahead.
