Kingdom Hearts 358/2 Days - ~Spoiler~ Don't you feel that Xion should have Kairi's head instead of Sora's?

At the end of the game, Xion is like, "This is what he looks like (Sora). That was gross. Anyways, I think it would have made more sense if she had red hair like Kairi's. She was built by Sora's memories of her (which is why she already looked like her in the first place.) She was a defective clone anyways.
