Blonde Bombshell curse/transformation?

I have a bit of a bimbo fetish but it's more retro tinged. I'd like to transform my girlfriend into more of a Marilyn Monroe/Jayne Mansfield type. More full figured but with a well defined wait, big boobs, and big ass. Also more dizzy and submissive. But not a full on slut. Also with an interest in only wearing period clothing and hair styles. Could this be done by combining some curses or could a custome one be made?
