IMO no this is not possible. Live players are quick to put people on AK and if he donks this river that's exactly what his hand looks like. Also, they never expect anyone to fold AK here so the raise would clearly be for value unless they are a maniac, and then they don't put you on a hand anyway so its sort of irrelevant.

Also you could argue to check/call river to induce a bluff but I think given the particular card that fell it will go check/check when you are good and he'll only bet when you are beat. So I guess if you think there are just too many combos that beat you check/fold is a decent play to consider too.
