Clouds should be procedurally generated and rely on the fact that they are above all geometry. In other words, all light data for the clouds comes directly from the atmosphere and does not require BVH traversals as we assume no hit. They should be able to move as a whole but deformation is not required.
Edit:
These kind of volumetrics are discussed in Ray Tracing Gems 2.
