Have you tried to make occults that haven't been added to ts4 yet?

I remember creating a blue fairy alien once ( using spooky stuff ). I was thinking of artificial intelligence when I made her. I haven’t used her though. I wish I could make robots that look like sims. In sims 2, I remember my daughter downloading some robot skins and I made some robots/androids with them, I don’t use CC or mods in the sims 4.
