This just popped into my head this morning, but what if someone made a model of Samus' Varia Suit from the Metroid games? I know it would be quite difficult to model something that detailed, but I think it could be done. Along with the suit itself, there would have to be a separate model for the Arm Cannon which would act as a blaster rifle of sorts, and that could be customized to act as Mira's Missile Launcher as well with a custom animation featuring the Arm Cannon opening to allow a missile or grenade to be fired. I'm also sure that you could create the helmet as a separate model, in order for the helmet to be removed, yet the suit will still be on. The helmet's visor can also be a transparent green, allowing the PC's eyes to be seen. Either way, I think you could make this for both KotOR 1 or 2, as I don't think it really matter which game you develop it for.
Thanks!
