There's really nothing about her personality (extroverted, wild, feisty, etc.) that's specific to one race. Honestly, I'd prefer that they try to capture the aesthetic of the source material as with Peter, Gwen, Harry, and Flash, but I wouldn't mind if they wanted to change the racial/ethnic background of the character to African American or Hispanic provided that the chosen actress really is best suited for the role and capturing the spirit of the character and it isn't just change for the sake of change.
I hope that they hold auditions for the role like they did for some of the other ones. Get a bunch of young actress (some that fit the mold and some that don't at first glance) and have them compete.
