@Thekillman Wood Release never made living/actual wood in the first place so I don't think it is a necessity to have Yang Release to create the trees, but if Yang Release was to be used in conjunction with the Wood Release: Advent of a World of Flowering Trees, or any other possible flower related wood release techniques, I think that would be cool. As for the dragon and the wood avatar, hmm... I don't really like the idea of them being senjutsu since I see that as being the equivalent of Susanoo and its weapons which aren't senjutsu.

There is a problem I see with your Black Rod idea, for the Gedo to give such an ability to the Rinnegan user it would have to have such kekkai genkai in the first place and while the Shikotsumyaku could possibly be possessed by the Gedo, I see no reason as to why it could or no reason as to why it could not, but it should be impossible for it to have metal release since it was given to Chmoei instead.

A light release does seem kekkai tota worthy but um... why do you keep bringing it up? The closest thing to a light release I can think of is Sage Art: Storm Release Light Fang.
