The Legacy of Zeb in the Ahsoka Series

I'm just trying to think of anything that I'd really love to see heir to the empire from that novel crossover into the Ahsoka series and do so without stepping on toes. But what's interesting about them is that they take place in the same timeline five years after Return of the Jedi and onward. Do you think they'll delve into legacy characters for Ahsoka? Well, we think Hayden Christensen is involved in the production. So that would present either Anakin or Vader or a combination.
