I like your idea of a river jam, I think it should net us more than checking down since we can fold out a bunch of Ax, 2 pair, and likely even sets vs most villains.

there are a lot of possibilities on that board, and one thing is most certain... you're not going to win unless you bet. your analysis about blockers is good, but does this player have a fold in them as far as his table presence is concerned?

I say try and ship it.

I don't think a reg will ever fold Ax on the river, especially when he checks the river (at least on the sites I am playing, must be different on PS.com).

I take my SD value.

It's probably close. It depends alot on your slowplaying frequencies. I'm not going to try to guess on the c/c range of a 17/13 in a SB vs BT spot. Its just too infrequent. GTO is the only way to go. 

What do you rep though? A flush is unlikely since so many of the high cards are dead and you might as well have raised somewhere, I'd also expect you to raise 2p+ somewhere before the river most of the time. And how do you frequently get to the river with KJ?

You have it going for you that you can hardly have any bluffs admittedly.

I'm not totally sold that KQ doesn't have some non-zero amount of equity to check back river.  that being said, if it's the same relative value as all other weak pairs in your range, then it's just a blocker exercise to find the best river bluffs.  I think you should definitely be jamming river with some pairs as bluffs, unless you think villain never vbets turn with AK (which is actually very realistic especially when you block Kh).
