Would anybody be interested in trading a PS3 copy of Injustice for a 360 one?

I have a XBox 360 copy of Injustice.  It's in great condition, had it since launch.  Would anybody be interested in even up trading a Playstation 3 copy for it (in good complete condition of course)?  I'm looking to exchange all of my fighting games for PS3 versions.  I'd expect the person trading to ship first unless they have good feedback on here in which case I'm fine with shipping at the same time.
