Could an "occult sim" (aka a Life State) be in a kit?

Under most circumstances, I'm gonna say that an Occult is too much to fit into a kit. Especially any occult with additional CAS features.

However, it is possible that they could expand Plant Sims into a more permanent Occult state with a kit, since it would be an add-on to stuff in the base game. And expanding Ghosts is another possibility.

But I don't think they could add a full new occult, even with just an additional pie chart worth of interactions like Aliens and Mermaids.
