I am not in that game, but I wouldn't recommend it. Turn 63 results will be certainly different [at least random events] and it will mess unit IDs, so if someone submits old turn 63 it can mess things up [really mess it up, like people getting some new commanders, some batles that shouldn't happen, mess with province ownership]. So if you do it be aware that you everyone will have to do turn 63 again.
