I do agree with Yashael341 on his statement, it would be a major hole in the plot that would have to be explained in a reasonable manner, not simply "I'm the most powerful villain and can bend the rules as I please" bit (that card got played out way too much with Aizen). What I'd be more interested to see if Yhwach uses Zenka no Taichi is a more in-depth explanation as to just how the medallions actually work (as well as what the Quincy actually call them). An analysis my Nimaiya would be even more interesting, especially if he can provide some insight into the state of mind of the "stolen" Zanpakto spirit. I can only imagine what he'd have to say about it, given the fact that he created the Zanpakto and would naturally have the best understanding of them.
