Keeping in mind what was said about using the Concepts' natures against them, perhaps steering mortal civilizations to grow strong enough, invoking the Law of Collective Aegis, to be able to challenge the Concepts and win, destroying them in the process. At the very least, destroying the Winnower in the process. It might be resonant enough with the Winnower's nature that the Winnower would go along with it, unable to help itself.
The trick would be incorporating enough of the themes of the other Concepts that they would go along with it in turn, even knowing that it would mean their own destruction.
