My sentiment is, and I presume the sentiment of others is, is that it would be great if you could take the time to learn how to do even a simple thing such as NPC modding. In my opinion, when people take the initiative like this, they are demonstrating that they care enough about the game to make new/different content. I like to see other people that care, personally, and I wouldn't want to see my efforts go into one person's 2-5 hours of enjoyment. I like to maximize my reach however I can. Also, I don't think people want to spend time making something as simple as this? I dunno, there's some people that might take up the request, it just isn't really my cup of tea personally.
