Darth Vader & His Inquisitors vs Ahsoka Tano & Her Squad
Assume for a moment that Twilight of the Apprentice went differently. The Inquisitors weren't killed and Kanan was not blinded, instead it ends with a climatic brawl at the apex of the Sith Temple, namely:
Darth Vader, 7th Sister, 5th Brother & 8th Brother
vs.
Ahsoka Tano, Darth Maul, Kanan Jarrus & Ezra Bridger
Who wins?
