Request: Paranormal Stuff specters as hats

I can't imagine this is too tough as they're just very simple meshes and textures. I just don't know the ins and outs of assigning bones/rigs to do it. I can get them into blender and move them up to the head, but that's where my knowledge stops so I figured I'd ask before I spend time trying to do it myself, assuming it's easy. :p

I just want them as a hat (that also removes the head if possible, although they fit snugly over the head anyway). I want to use them with an invisible body to make playable specters!

Edit: This request is for adults, but it'd be a nice idea for kids too. Possibly even better.
