Would he have folded Aces?

as a (85.2%) 5.76:1 favorite over a random hand, the only thing that changes is the "ev in calling" from your previous post, which rises to 0.852*0.9*12000=9201, and so adding in the loser's prize, it just BARELY squeaks out folding. Play. Psychologically, for your mental health I recommend a call.

Amusingly KK is a losing play, by about $100.

Well, there is definitely a time to lay AQs and sister hands, and that's it. as he said, his M was > 22.5 (assuming no antes), there's just no reason not to wait for a better spot.
