You can't both assume you know him well enough to know he'll fold a strong ace on an ace high flop in a 3bet pot AND think he can assume you have weird suited crap because you have no history.

People don't fold strong aces on ace high flops in 3 bet pots unless you have a strong read that they can make big folds. That's why they raise AK preflop, to hit an ace. You're essentially expecting him to fold all bar the very top of his range on the assumption he thinks you could have suited crap OOP in a 3bet pot, and that you'd take this line if you did.
