That's what I'm saying. Changing Chakra nature is not as simple as adding more Yin or Yang, thus combining Basic Nature Transformations with Yin or Yang Release would not cause the creation of an Advanced Chakra Nature. If that were the case any ninja with sufficient skill would be able to perform the techniques. Manipulation of the Spiritual and Physical energy within one's Chakra may not be basic, but it's does not require and affinity either, and Yin and Yang are not Chakra Natures themselves. Thus mixing them in won't result in a new element.
