This arrangement retains six spheres for adjusting the style of terrain in each substitutions set. They fall into three categories:
The first is either hierarchical hills (tree-tree) or craters (shell-shell).
The second is a shell-tree, which is a combination of hierarchical hills and craters. Hills or craters can be inside hills or craters, but they don't overlap each other's edges.
I'm not sure the class of the last type, I think it is still a shell-tree. It uses overlapping hills and craters to form a landscape primarily out of connecting ridges and valleys.
Examples left, middle and right here..

I'm most interested in this third type as it seems to be a bit closer to natural fluvial landscapes of ridges and valleys. I can now add one of these types to different generating spheres of the icosahedral set that I showed. A white version of the ridged structure for the northern pole mountains, a green version of the tree-tree on the left for some canopy, and a brown version of the shell-tree on the right.
