Standard river aggro?

Villain is LAG, been very liberal with button stealing and will do it with almost any 2.

Is the river 3-bet a bit much? I thought about a river c/r instead but would really hate it if it gets checked through, and thought there was a decent chance he would raise with many hands I beat, including a K or Q.
