I have seen it done by someone here and it was a lot of work. You have to squeeze 2 ESC's and a fair amount of wires onto the frame. It did not look good and to be honest, why do you need that? I upgraded to the Xtreme motors from ushobbysupply.com or boomtownhobbies.com and they were more powerful and a little lighter then the stock ones. With the 850mah battery it flew about 10 minutes. Brushless just seems like overkill. I would spend the brushless money on a fixed pitch machine like a honeybee for $100.
