Even if you could technically make it work, I'd be very nervous around the legalities of that. Or is the Wi-Fi spectrum so unregulated that you can run without any certification at all?
WiFi equipment (and pretty much every other radio) requires certification in order to be sold in every country I am aware of. WiFI doesn't require a license to operate, but that doesn't mean you can just use any hardware you like (though I think there may be exceptions for hardware you build yourself, at least in the US).
