Trying to move someone off the nut low may be a viable option against sophisticated opponents but in lower limit games it is unlikely to work. If you raise it should be to as a bluff for the high side or to set up a bluff. Otherwise your better off leaving them in so you can possibly make a profit on the river bet. Even if you could push out another low the pot is fairly small so commiting a lot of chips with the goal of getting half is risky if you get 3/4'ed.
