Reading this, I think that, at the core, both Inoue and Yhwach's powers are related. They are both humans with powers that transcend the very laws of nature and it would be very plausible that she is one of the Powers... I don't think Byakuya could be one of them, I know, he's extremely talented and powerful, but in a, how could I say... "standard" way. All the others have traits that really makes them unique (Ichigo the only hybrid, Aizen the only immortal, Zaraki the most powerful ever).
