Hard to say. The answer has been a bit contaminated since the late 1700's because of Gibbon's attacks when he wrote "Decline and Fall of the Roman Empire". I strongly suspect that the results would be exactly the same, modulo the butterfly effects, meaning everything would be totally different in every possible way. Actually we have 'zero' clue (and we never will) know how sensitive history is to 'thermal' noise, as we are stuck running N=1 simulation.
