Highly likely, no. The encoding and frequency assignment used by these toys is usually very different to that used by WiFi. Ive been flying model aircraft for years and what your asking is not easy if not part of the original design. The cost could be more than buying another. FYI phones, tablets etc make awful controllers hence why anything above 'toy' status uses a proper proportional transmitter. Also WiFi has a tiny range in comparison.
Also remember flying a drone out of line of sight is illegal in many countries (I'm UK based and its illegal here) so adding a camera and live feed does not mean you can fly the drone off all over the place out of sight flying by the video feed. If your really interested in these thing and are UK...
