XBOX360 and PS3 HELP :D?

So, I want to trade in my PS3 and games for an XBOX360. I have the system, Battlefield: Bad Company 2, Modern Warfare 2, and LittleBigPlanet, 2 remotes, and that's it. Could I trade all this in for 1 used XBOX system, 1 remote, and maybe 1 used game? Also, don't ask me why I want to trade it in.
