Sims 4 Spinoff Theme?

Journey to Batuu showed us that they don't really need to do spin offs. I would be happy if they added everything sims in the main game as EPs. They could invent the time traveler packs or something and add Medieval and 50s and Victorian and castaway to TS4. Make them double the size of an EP if needed and and add everything to TS4.

I would love the following:
1. Ancient Egypt with Mythical Creatures
2. Ancient Greece with Mythical Creatures
3. Dark Ages with Camelot
4. Medieval Times with Dragons
5. Georgian/Victorian with Western
6. Castaway Reclusive Island with Genies
7. Prehistoric Stone Age with Dinosaurs
8. Futuristic Earthlike World with Flying Cars
???

I need Sims Medieval (or Renaissance would be cool) to happen again.

I liked Castaway a lot too and would play that if they remade it.

History x Mythology would be so cool

I like Sims Medieval but one thing that always bothered me
is that we didn't really get to explore any other kingdoms in it
there was just that one castle and one kingdom to play in
even though it was constantly hinted that other kingdoms exist

also, not enough occults to play and no dragons :( those should definitely be part of it

also I do think stone age/cast away/ dino island/ sea voyage/ space travels etc kind of spinoffs
would be fun adventure since sims life in base games is always so very conventional

Oh, how about something fun like Sims x Spore
where sims find themselves living in most mysterious circumstances on planet Sixam

Castaway.

Cyberpunk

Love most of the ideas
But personally instead of a spin off they do a pack and bring them to TS4
