Pompey could have done what Sulla did, but he was a political idiot - lots of money, little actual political nous.
Could he have made the right allies? I can see, for example, a TL where he's victorious as Pharsalus, then forms a new triumvarite with Cicero and someone else (maybe Cato?), leaving his allies to form the details of the political reforms...
