Non-buggy hybrid sims plus more species please??

PLEASE add hybrid sims! First of all, i wanted to buy realm of magic in the hopes that i could be a spell casting mermaid. I in fact cannot be a spell casting mermaid. That disappointed me. When i first heard of sims it was sims 3 that made me interested, and one of the features that interested me the most was hybrid sims. I would love to be a mermaid spellcaster, i would love to be a mermaid-vampire-fairy thing. You know what? I’d love actual fairies, with loads of different wing designs and all like in sims 3, maybe a fantasy pack? Not a mod! I have so many suggestions lol, but my main want is the ability to play as a hybrid! I wanna be able to make one in CAS but also have a sim become a hybrid through my sims gameplay journey. Probably only between two species… like a spell casting mermaid, but also a vampire mermaid or vampire witch like in The Vampire Diaries (which I think was already used to inspire the vampire pack.) You could let us choose which parts of physical features we want to keep in CAS and have specific conditions for each combination in terms of appearance (human complexion but with fangs, cant gain tail in water while in werewolf form, etc) Basically the combination of any two species available in the sims 4 (with the additions of more species!) I requested this several months ago too, to no avail. 🙏🏻
