Modding Request -- Hat Chops

I'm desperate for a version of this clayified hair with hat chops, specifically for the cowgirl hat. The original creator mentioned in the description of the original post that, quote, "due to the hair shape" it won't work with hats. This could be true, but still I tried to at least attempt adding hat chops myself, but I couldn't even import a hat mesh into blender (I'm, like, newer than new to meshing-- beyond basic recolors I'm currently useless at cc making). I don't know anything about either creator's TOUs, so if either have an issue with someone trying to modify the mesh than I'll understand. I'm also open to any tutorial links for adding hat chops in blender, but bear in mind I've already tried to follow three or four different methods with zero luck. Thanks in advance to anyone who can help!
