Yes, I suppose it's doable. |

Why hasn't it been done already? I don't know much about this, but I would guess brushed DC motors are used because of: cost (hand held fans cost about $3), low voltage (hand held fans typically run on 2 AA batteries; about 2.5V), and power (brushless motors are better suited to high torque/power applications). |

But I admit it would be pretty cool to use a fan with a power/weight ratio which would allow it to fly away. |

I don't know enough about electric-motor design to know if there's a big difference (and Google came up with a couple bake-hits as well) |
