That wouldn't give you anywhere near the resolution of an actual hot wire anemometer. I'm fairly confident your instrument would be limited to measuring "is the wind below or above 60 mph?", and would be unable to resolve changes happening in less than ~ 10 seconds. Real hot wires have a diameter of ~ 1/100 of a millimeter, that's the only way to achieve any useful level of sensitivity.
