I don't think that would be a problem. I believe all you need to do to make a category is to add it to the page you want to add it to as if you would an already established category, then you can click on it and edit it from there, with established guidelines.

It has been a while since I made a new category on a wikia, so don't quote me on that, but I believe that's how it works.
