If it is possible, you would be severely limited by the WiFi signal radius. I'd highly recommmend a normal 2.4 Ghz TX since they're designed for this stuff. The phantom comes with TX, but if you go the DIY route I can really recommend the Turnigy 9X from HobbyKing. It's only $60, has 9 channels, comes with receiver and people won't laugh at you because you're holding an iPad or a toy-like transmitter.
