Any character created before the rule went into effect is safe, they were grandfathered in and don't need to be changed, so Shiroi having Bankai isn't an issue unless you want to submit him for the exam. Once you pass the exam, you can re-add anything you want to his article.

As for the character you submit for the exam, you can choose a character and change them up, or make a brand new character. Simple as that.
