Too weak IMO. In order for you to be beat on the turn, opponent has to have a better low *and* two pair or better, which is a fairly restricted range of hands. I would give opponent credit for A23x or AAxx; in either case opponent has only about one chance in four of having you beat both ways, though A23x could obviously also be freerolling you even if you still have a better high on the turn. Anyway, if you call turn and (presumably) another bet on the river, you pay two BB and (if you are still good for half) get back 4.4BB - so you need to be good for either high or low half the time, and I you'll probably be good more like 2/3 of the time.
