And it is possible for each go to be the reincarnation of kaien because the Espada he was killed by doesn't take their souls it takes a portion of their power and DNA allowing him to replicate their image as long as he's in the shadows and another theory on how Ichigo has so much power as if you read the Manga Ichigo contains the nine years power built up by the Quincy King that he was never able to regain because the fact that ichigo's mother was killed before he could take the power from her.
