I'm guessing you mean is it possible to force carb with CO2 and then use a nitrogen bulb to dispense? I would be guessing the answer is no (or rather, it'll dispense, but you won't get the notrogen-like head). Normally you use a nitrogen/CO2 mix at a much higher pressure than CO2 alone because the solubility of nitrogen is much lower than that of CO2, so the pressure has to be higher to get any of it to dissolve. I doubt that you'd be able to get the pressure up high enough with those tiny bulbs. Have you used CO2 bulbs before? You don't get very much pressure out of one... I found that I had to use four bulbs to dispense one 19L keg, and the flow rate was much lower than it is with my standard CO2 bottle.
w00t!
