Expanding aliens, Sixam and alien lore in the Sims (expansion)?

Interesting idea, but given the fact that we got aliens in Get To Work, I think most simmers would just be upset, if there was an expansion pack to devoted to them, especially since most Sims 4 expansion packs don't include a new occult like they did in the previous two games. Remember how upset some people were that Vampires were in Supernatural since they had bought Late Night just for Vampires?
