Yin and yang can't be considered elemental but i think they can be combined with an element or more. Assuming so i can think of some kekkei genkai: Other than Blaze release explained before (Fire+Yin). Black Lightining is Thunder+Yin Crystal Release is Earth+Yin. Yin help to encase earth molecule in a perfect structure. Wood release for me is Water+Earth+Yang chakra, only two element but with the addition of yang chakra to make the wood "lively", otherwise it will be some sort of Mud release.
