Twins and triplets with the same Zodiac sign

I'd love to have zodiacs back even if they carried zero weight. just having that extra lil detail to differentiate sims would be nice. I was just thinking earlier about if sims had a fourth trait (or fifth I guess if you include their aspiration one) that was their zodiac. like when babies are born it's with one trait (their zodiac) and go from there. not sure how viable or sensible that would be though!
