Very standard as played up to river, and I think river is a very easy fold. Think about all the hands you can arrive on this river with, and as you outlined in the OP fairly well, AxKc is one of the absolute worst possible ones to hero call with. Also remember that facing an overbet we have to call much less often than facing a "normal" bet (MDF here is only 36%).
So we only call here with AxKc if we say this is a live exploit spot where you just hero call ~100% of your range (and trust me I'm all for live exploit spots where we do that!), but unless I misinterpreted the OP, it seems you think your opponent is equal skill or better than you, so it's probably not the time ESPECIALLY since you said what you think about villain, but not what he thinks about you which is super super key information if you want to go for a extremely wide deviation.

Flatting AKo is definitely not "weird" here, but if you meant difficult, then OK lets say you make it $300 and he calls, you have $1700 behind in a $600 4-bet pot, is this not also a difficult spot?
It does suck to put in so much money and lose a big pot, but remember you'll hit TPTK with AK roughly ~50% of the time, so sometimes it happens and it's better to lose $250 in this hand than $950!
