Well the idea of Blaze being yin+fire actually kind of makes sense. however, it seems a lot like a Pseudo-element to me, and not necessarily a "true" element that stands on it's own.

What i mean is, Blaze is essentially more fiery fire. It burns anything, but it doesn't do anything special. Scorch could turn people to mummies in stead of burning them to a crisp, suggesting more of a "hot air" jutsu than just a "hotter fire" jutsu.

So it seems to me that Yin and Yang may act as "amplification" of an element, rather than forming a true new element.

As to the topic at hand, now that Amaterasu clearly isn't Lighting+fire, the thing that makes most sense to me is either Light Release or "star" which i would describe as firing shocking bolts of plasma (but doesn't have any catchy, descriptive name).

As to Lightning + Air, i'd say sound (or more generally, Tremor) would work. Mostly because Sound is a vibration through air, yet it can just as easily make vibrations in the ground or in liquids.
