Who would be better?

Rosalie Hale is suppose to be the most beautiful creature that had ever existed. I honestly dont think that Nikki Reed with Blonde hair works for her, makes Rosalie look like a joke. Nikki is only beautiful as a brunette. My question to you guys is who do you think would play a better Rosalie? My choice is Mena Sevari. She hot, looks great as a blonde. Great actress. I think she would be great.
