No. Everyone who has chakra from all 9 bijuu has that mark on their back.

Your theory is outright debunked by the source material, and you dont get to hide behind the word "theory" if you choose to believe something that the source material says is incorrect. That is fanfiction.

Theories are based on observable facts and/or patterns. When information disproves your theory then you rework the theory to accomodate the information, not the other way around
