Perhaps not out of the question, but *highly*unlikely. If the faceplate/funnel/shadowmask/phosphor were not usable, the best option would have been to simply scrap the tube!
It is a VERY labor intensive/time consuming process to cleanly separate the faceplate from the funnel, remove the remaining frit and prepare (lap and acid fortify?) the faceplate for re-deposition of the phosphor... MUCH cheaper to use a new part.
