volume blending of distance and height fog settings

I'm considering writing a custom fog effect for the v2 post processing stack, which would allow distance based blending of volume settings for distance and height fog in deferred rendering, (and ideally a volumetric fog solution, but that will depend on Xbox One performance). I just wanted to check here that what I am planning to implement isn't already supported, because it strikes me as a fundamental feature for the distance based volume blending feature of the v2 stack, and I don't want to duplicate work. The various fog solutions just don't seem well integrated with the new post processing stack.

 

I'm looking for some kind of height based fog solution. The post processing stack's deferred fog is distance-only. Did you ever get around to creating something like this?

 

If it helps anyone, this is a post process fog effect I wrote for the v2 stack:
