Even if you had a seperate controller, it will not work on the network with the same licence key; it will work on its own; you will both not be able to play on the same server. Likewise I wanted to do the same with my son; eventually I bought two copies of G2 to make it run on my network.

On a side note; we only played on the network a couple of times. Now my son prefers to come and play on my machine as he likes to take turns. I fly, when I crash, he flies. I usually end up crashing. My son usually ends up handing it over to me as he rarely crashes. He is 17 and doing great.
