Why would any studio give themselves the headache?

Any change that a studio would do would cause fans to bitch incessantly about how the white actresses weren't accurate to the show. Never mind that all of the girls were coded as Caucasian in the Manga and both TV shows, anyone that isn't Asian is not accurate to the source.
