Need to make a cloned hat basegame compatible [SOLVED]

Hear me out, first, please. I'm not talking about making content from an expansion pack available to people who don't own that expansion pack. It's not that at all. I made a hat and it's one that sits straight on the head. The problem is that the only toddler hats I could find to clone that sit straight on the head comes from packs other than the base game. I'm wondering if there's a way to clone a non-base game hat and alter the package so that it requires the base game or if I can take a base game hat and alter the package so that it uses the hat chop for hats that sits straight. I hope that makes sense. 

I'm thinking I need to alter the region map. I might test this and if I'm right I'll mark this as solved. 

Edit: Well, that was fast. And easy. All I had to do was go into the region map area and switch the hair mesh from HairHatB to HairHatC. Now the package is using the right hair chop.
