I'm looking at the facts and telling you that I feel the devs thought of everything to make sure this doesn't happen, as I mentioned in the thread, unless there was some kind of bug I'm missing it pretty much appears to be an impossible feat unless the information I got was wrong but FF Wiki is pretty thorough about information.

His stats are maxed out as well, so even with better equipment he could still be one-shotting your characters. He can be silenced and blind which will stop his offense from being too effective but if Tornado is a scripted move then you still won't have enough time to damage him.
