It would seem very unlikely since Kubo wrote a different story after finishing Bleach (BURN THE WITCH, also set in the same universe) and that is going to be serialised and animated later this year. It also seems a stretch for Kubo to write a story with such young lead characters, so it would need to skip ahead a good few years which would probably kill a lot of peoples "ah theyre cute factor" level of interest.
