C'mon guys let's be cool, alright? The more the merrier! Besides, if she wants to be Sora then she can be Sora. There's ALWAYS multiples of characters at cons so I don't even know why this would matter. Besides having more than one of a character is usually a GOOD thing. It can open up oppurtunties for different photos, can make it so if one person doing the cosplay doesn't show there's a back up, etc. Let's all just be nice and live and let cosplay, okay? :3
