I love it when questions have too many variables to actually know for sure.

I have to say yes its possible (at least on the CP), because i have not seen it proven otherwise yet.

The weight of the equipment and the lift of the heli are really the main factors (conditions also matter).
Increase lift: stronger motor, more volts, better esc, faster headspeed, larger blade diameter, more pitch.
Decrease weight: buy/build small cameras, small transmitters and batteries or a circuit to tap into flight battery pack. Strip excess weight from cameras circuits and heli, cut down useless stuff, etc...

In fact i think the CX could do it too...
