KI on PC Modding

Are their any plans to make KI accessible to modders? I’m a veteran 3D artist and I’d love take a shot at playing around with textures, models and other such stuff. But at the moment I’m having a doozy of opening up the .PAK files.

Also I guess this would be the time to field the basic modding questions, will modifying texture files and the like cause a red flag on XBL? As much as I’d love to tinker with the game I’d rather not risk a ban from XBL over it.
