I want to be able to create superhero sims that can transform between two different body types (like the Hulk), and the only way I can figure how to do so is by making them aliens and switching between the two forms. But if I do this, they talk like aliens, people react to them as aliens, and they have all the weird alien features.

Are there mods that let me “remove” all traits and occult features of the alien mode (especially alien reactions from other sims), so the only thing left is being able to switch between two forms? Or is there another way to let me transform between two body types that doesn’t require using the alien occult type?
