Your thinking is flawed mostly because non of these "draws" you speak of, have air and will need to bluff this river. Tell me what draw you think he has that will need to bet this river?

You think he's suddenly gonna wake up and raise a worse two pair hand on this river? It's very unlikely that AJ, KJ or anything like that will raise this river.

I don't really get the value in making your hand "look like KQ" when all the hands that will value bet versus a perceived KQ will call a river bet anyhow.
