In Caliborn's masterpiece, Jake lands the final killing blow on Lord English when he fires up the ol hope engines. I'm guessing that was him becoming a fully realized page of hope? What do you think tavros could do as a page of breath?

I mean he didn’t land the ‘Killing Blow’ because Caliborn can’t be killed at that point so Dirk had to seal him later. But yes it was the “HOLY SHIT, HERE I AM, LAYING ON THE GROUND, DEFEATED AGAIN” blow.

As for Tavros, eh. Something big and windy, sure, but part of the Page’s powerset is, in fact, on how they make people follow them, and Tavros getting the Ghost Army together in the end is pretty much the most miraculous Act he could’ve pulled off towards the end.
