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.
Also, the guy can destroy a cannon the size of a building with just a spear, and that's on the LOWER end of his stunts. I don't think he needs the extra juice of a potentially dangerous transformation, guy seems plenty powerful as-is.
