Kubo can make it in between too.

He could make Ichigo fight Yhwach and deal him a lethal blow to the chest. Then, before we get any conclusion, he can draw a few chapters and have Yhwach think back to the past.

How he created the Quincy and what he planned to do, plans which were temporarily stopped when he was sealed and continued when he was free again. His thoughts around things like the Auswählen and stealing the powers from Gemischt Quincies, which i doubt he has any remorse of. His thoughts around Haschwalt whom he seem to be a bit close to in contrast to the other Stern Ritters, how he actually gathered them and whether he gave some of them powers they didn't have.

When everything is revealed and made clear, Kubo can return to the moment of the fight, and Yhwach refusing to die without fulfilling his goals. And then, more fighting where Ichigo deals him the final lethal blow, and Yhwach realizing that he failed in the last seconds before he dies.
