Flipline mobile games

Has anyone ever thought of modding these games? I’m not sure how hard it would be to change mechanics and stuff, but it seems cosmetics are pretty easy to change. I took a quick look at one of the games, and they still use flash. I experimented with changing one of the customer’s appearance and it seemed to work fine. I think it would be cool if there was a weight system, similar to the star system already incorporated, that changed the customer’s appearance based on their level. Then again, I don’t know what amount of work that would take.
