Queen cells are very delicate. I start mine in a starter box, and transfer them successfully into an incubator at home, but it is not 2-3 hours. My time frame is about 15 minutes, and driving very slowly. If they become unattached to the upper portion of the cell, they will die.
But then again, it is your experiment, and you are not really losing anything, except a swarm. So, I don't think it will work personally, but give it a shot. Maybe, if they are very close to emergence, you might get away with it.
