Is there a way to put the typical FPS rig in front of you using the Game Animation Sample Project?

I want to use the running and climbing mechanics from the Game Animation Sample but use a FP camera. I would need to see/use my arm and hands for combat. Is it possible to do this? I’ve already made the camera FP. Is it simply moving the arms in the viewport? Or would I have to remove the arms and add my own animation in? If I do that, wouldn’t it break the climbing mechanics? Any help would be great!
