Bluff-raise river against 2p2er?

[StrictlyStrategy]

2p2er is Kit. Not long ago he raised and I 3-bet and he folded on an A high flop. He just lost a big pot and I think he might be steaming so I try this.

He raises early and it folds to me and I 3bet QJs in the CO. HU
KTXr I raise the flop and he calls.
Turn's a 2 and he check calls.
River's non-pairing 5 and I can't imagine he has anything so I raise his river bet?
