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.
