From what I've read, heard, and seen about exos it that they can be brought back, but without their memories. However, the dead exos triumph has you extract memories from long deceased exos. What if you could extract cayde's memories from his dead body and put them and his mind into a fresh exo body effectively reviving him, however without his light... I want to hear some opinions and if I'm wrong about this please do correct me (I am aware that cayde requested that he not be brought back)
