Can we have ahsoka tano in Star Wars battlefront 2?

You make some very good points and to be honest I think you're correct in saying that her adult form would make more sense when she is matched up next to Vader but my problem with that is her adult form appears in Rebels which I believe (and please correct me if I'm wrong) takes place some time between ROTS and ANH. If I am correct the only two pieces of Star Wars canon that take place during that time is Rouge One and Rebels so unless Battlefront 2 specifically utilizes those setting I feel as though young Ahsoka would fit better with the setting. She was an important part of the Clone Wars which was obviously a part of the prequel trilogy so in my opinion that version of her would be a more natural fit for the setting. Also to your point, I like her character design in Rebels but I don't like the art style of the show.
