I don't think that the Scrolls work like that. My understanding is that they show the past as it happened and all possible futures. In Skyrim, we were able to see the ancient heroes fight Alduin with Dragonrend, but they were not even aware of our observation.

Besides, that war was won. no need to fight it.
