What is Ghost Armor? If it is a screen protector you should have no problem. Maybe I'll go look it up and find out what you're talking about.
It sounds cool, and like a good thing.
Edit: Ah! It is a screen/body protector! Did you see these threads?

The Ghost Armor looks a lot like the Zagg or XOskins to me. I think you can still get the XOskins cut to fit either eDGe.
Good luck!
