The so-called Hollowfication experiment was not, in essence, conducted by finding a Hollow with power equal to that of a Soul Reaper.
The Hollowfication experiments conducted on Shinji and the others back then did not involve particularly powerful Hollows either.
Even White Hollow inside Ichigo had merely touched the threshold of Captain-level power, and could only suppress a Captain before Bankai for a time.
From this, it was clear that breaking through the limit did not require two forces of nearly equal quality.
What was lacking was a medium—a medium that could open the sealed gates of the limit.
Soul Reapers and Hollows appeared to be two entirely different kinds of beings, but in essence, both had transformed from humans.
This was most obvious with Soul Reapers. Once a human soul underwent systematic training, it could be called a Soul Reaper.
As for Hollows, they were human souls that, because of their lingering attachment to the Human World or other obstacles, could not ascend and instead wandered in places that attracted them.
Some of them, after years of torment and resentment, or under the acceleration of outside factors, eventually fell and became Hollows.
That was why a Hollow's spiritual power was often filled with all kinds of negative emotions.

Most importantly, only a dozen or so Netherworld Seals remained. If she didn't eat them... If she didn't dismantle them, it would be troublesome if they happened to be detonated.
