There is no scan of course except maybe madara. Last I checked storm release is not any of the bijuus KKG's. Yet madara does it but I will ignore that.

If one thing already breaks that rule then the manga saying the rinnegan can do "any" tech must be true.
The rinnegan itself is a KKG. If you remember it's gotten by ashura + indra chakra = hagoromo's chakra. So in the process of getting the rinnegan, there is a fundamental change in the user which would allow them to use any ninjutsu including KKG.
