Which SATC characters are the Vanderpump girls

So me and my dad are watching season 5 and trying to figure out which of the sex and the city four are the Vanderpump girls (Stassi, Katie, Kristen, and scheana)

We've come up with...

Kristen is Samantha Katie is Miranda Stassi is Carrie And scheana is Charlotte

I think our list is pretty good, however scheana isn't really a Charlotte imo because she's not as chic/classy as Charlotte and scheana is a terrible person 😭 but they both were desperate to get married and they both have dark hair and idk who else it could be!

Stassi has to be Carrie because she has a complicated love life, she's the main character, and very fashionable

And im sold on Kristen as Samantha and Katie as Miranda (Schwartz is such a Steve...)

What are your opinions ? And who is the rest of the cast?
