That is what I wanted to do, but I am a newbie at modding and couldn't get this to work through steam (TSLRCM's files were just overwriting my files). My solution was to include the whole TSLRCM package with my modified files in the steam mod. That is why I wanted to ask first, because its not just copying the files I want to change. I would be copying everything, tweaking a few files, adding a few of my own, and releasing it like that. Obviously that would not be okay as a public mod, but it still seemed like a gray area sharing with family and friends.
