What if Bloodraven is a wight?(Spoilers Extended)

Lack of TWOW induced insanity but shortly before we meet him Leaf confirms Cold Hands is a different type of wight(they killed him long ago). Then a lot of the physical descriptions of Bloodraven sound like a literal corpse, dry paper thin skin, facial bones exposed, a root growing through his skull.

Is Bloodraven a dead corpse being animated like Cold Hands?
