Hmmm... how to phrase this... Trying to figure out this power thing. I suppose one could read the chapter as Yhwach being able to transfer a "power" from one Quincy to the other. From what it seems now, this doesn't seem to entail that the revived elite Sternritter get a whole array of new powers (such as Le Vaar getting Bambi's power or Bazz-B's power on top of his death dealing), however, it seems the "potential power" of elite Sternritter-x is being enhanced. Tremendously. The question is until what level could the elite Sternritter gain more power? It kinda feels they are just some sort of vessels in which Yhwach's/Bleach universe's potential energy can be stored somehow. Perhaps it's the Quincy itself who determines the use of this potential power (like a heart/soul thing as we saw previously). Perhaps this is also part of what Yhwach really is: he is (part of) the source of potential power. Auswahlen is a mere concentrating of his potential energy, which was previously stored in (other) Quincy. Once he transferred all of the potential power back to himself he might not be able to contain it, and therefore may need the help/body/soul of the Soul King. If so. What would you want once you got all your potential power and possibly the Soul King's? What would you do with the Hollow? Obtaining that what Ichigo essentially is (and perhaps his sisters as well)?

Also, I still think there is room for some extra dimensions in order to explain "power" not being reishi. We cannot perceive that of higher dimension, aside from magical (dis)appearances out of nothings.
