Another plot point could be their relationship development. Since they are traveling through time together, they might rely on each other more than before. In some fanfics, this leads to a romantic relationship, which is different from their platonic relationship in the original books. It adds a new dimension to the story.
The changes they make in the past and how it affects the present and future is also a major plot point. For instance, if they prevent Voldemort from getting a certain power in the past, how does that change the wizarding world they return to? This exploration of cause and effect makes for a very interesting read.
One interesting plot point could be how Salem's time travel affects the balance of power in the RWBY world. For example, if she goes back in time and allies with certain villains or undermines the heroes in their early days.
One interesting plot point could be how the Rokudaime (Sixth Hokage) interacts with the past characters. Maybe he uses his knowledge of future events to prevent certain tragedies or to change the course of history in a positive way.

If they change something in the past, like a major event involving the Malfoys and the Potters, it could have huge consequences. And the exploration of time - travel magic itself, like the spells and devices used, is always fascinating.
A third idea might be that both Harry and Teddy accidentally travel to a time in the past where a great magical event took place, like the founding of Hogwarts.

They might even learn some long - lost spells or magical knowledge during their time there.
