Long story short: it won't work. First you would have to convince the device with the two wireless interfaces (the windows PC I suppose) to send the packet on both path. Good luck with that: your typical routing software, including the one in the windows kernel, will choose whatever route it thinks is faster and stick to it. At most you can get some sort of load balancing but it's not what you are describing. If you somewhat manage to duplicate the traffic, TCP should handle that without problems. The impact of dropping half the incoming packets on network performance remains to be seen, however. UDP on the other hand has no way of knowing the absolute sequence of a packet (it's the whole point of UDP after all) and it's left to the in game protocol to deal with duplicate data. I suspect it will fail at some point, defeating the purpose.
