Cloning the object.set_as_head Console Command

I'm wondering if there's any way to clone the object.set_as_head console command and change the target bone from b__Head__ to b__Spine1__? It sounds like a fairly simple thing to do, but I'm not very knowledgeable about script modding. I'm trying to create an animated object that is applied through this kind of command. Any advice would be greatly appreciated!
