Name changer?

Hey guys, I'm fairly new to MPGH but not to game hacking in general. But I was wondering, is there a way to change your name in the lobby? I made a private name changer on MW3 and my friend made one for ghosts (he's the fuck cod guy) but won't give it to me because of security reasons. So, if you could help, that would be awesome. And if it helps, these are my PC specs, 2xNVIDIA GTX 780's, Intel Core i7 4770k, and Asus Sabertooth z87.
