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 feel that he could transform, but that without full on access to an unsundered soul like Nidhogg's it would take a toll on him. As physical transformations seem to use a lot of aether. For even not every Ancient was able to physically transform if Hythlodaeus was being truthful and not extremely modest. Though Estinien seems to have kept the ability to use temporary physical clones of himself after said possession and do a huge stardiver/drg lb3. It's been a while since I saw what he exactly does to finish the fight with that experimental ultima weapon in that echo flashback.
