All of your post was interesting but I wanted to answer this paragraph. The explanation of why Jesus was seen after the executions could be that he lived. I like the Cornish tradition that he was taken there by Joseph of A. The spear thrust cleared his lung of fluids and blood so that he could breath more efficiently. He was taken down and away and like Josephus's friend he survived. He was taken North to the Ports of Sidon or Tyre, which had traded with Cornwall for tin for a couple of millennia before Jesus's time. On the way he was seen by many old friends and acquaintances. He was exiled.
