ModMo123456789

I know, I know, its probably one of the dumbest ideas out there(and if I could do it myself I would) but everytime I see the dancing lion, I cant help but think how funny it would be to see his head replaced with Freddy Fazbears from FNAF and hearing his scream in the cutscene. Is this kind of mod possible??

Ive been trying to do thiis myself, but I cant manage. So I figured Id get help from the more experienced modders out there. Has anyone made this kind of mod yet? And if not, can anyone make it?
