Yes possible to achieve. I don't fully understand the question (well above the round, and the smoke layer), but assuming it means you want different layers of noise at different heights in the atmosphere, you just need to set up the geometry for each layer as the most intuitive way of doing it, and apply a CoronaVolumeMtl to each (probably a different material for each so you can control the settings independently).
(You could probably do it with the Global Env by using clever combinations of the Corona Distance shader, but I think the geometry approach would be the most manageable, intuitive, easy to control and visualize, etc.)
If you don't mean different layers at different heights in the atmosphere, let us know :)
