We already know the Uchiha and Senju inherited Yin and Yang, I'm just saying. The manga never stated that another nature couldn't be created by manipulating Ratios of the same chakra, though it does talk about Ratios, as seen when Sasuke used his Sharingan to match his own ratio of chakra with Naruto's. I'm not saying its impossible, I'm just saying it was never stated that Yin and Yang couldn't make advanced chakra natures when used with elemental chakra natures.
