If the Romans had been victorious, it's likely this would pass the way similar incidents had. The MO was the standard Roman one - come down on revolts fast and hard, even at considerable risk to understrength units. A Roman victory would have meant punishment for the guilty parties, possibly a considerable amount of tribute taken from Jerusalem, and a continuation of the underlying conflict. This could get especially bad if the zealots decide to still duke it out (not improbable - they'd aölready killed the high priest, massacred probably tens of thousands of gentile civilians, and murdered the garrison they had assured safe conduct). Gallus was not exactly a kindly man, and he would be back the next year to invest Jerusalem. He might not end up burning the temple (that was not part of the plan anyway), but he may well choose to let his troops loot it. Remember how well Pompey's visit went down with the locals? Exactly.
