Good luck, several of us are interested as well. I do know that these guys did it (aerialmediapros.com) but aren't saying much about it. Another poster commented that apparently they didt get the pitch axis to work properly. I think, it also didn't feed the live view anymore either. Surely its only a matter of time before someone figures it all out. Keep us posted on what you find, since you've at least taken steps towards working on it.
Dronefly.com apparently did something as well according to another poster, but I haven't seen or heard about their results. perhaps they can answer a few questions for you.
