What is Oshō doing right now ? Would his power have returned yet ? And if so, surely he would've healed/tended to the rest of the Royal Guard by now ? Then again, such a broken zanpakutō in the final fight probably isn't fair against anyone other than Yhwach or Ichigo.

Yhwach still has Yamamoto's bankai doesn't he ? So he could use the necromancy technique to summon some fodder for the small army to chow down on. Imagine if by some hand-waved reason, Yhwach was able to summon an undead Yamamoto...
