It doesn't have to be trivial. You can disable mossy in the config and use the chisel moss balls, which require resources to make.

Mossy Cobblestone seems to be handled exactly as desired: Cobblestone, in the chisel, does not offer mossy cobblestone, and has about 16 varieties of mossy cobble stone. Regular cobblestone in the chisel likewise has 16 varieties of regular cobble.

Its Mossy Stone Bricks that are the problem: There are no chisel varieties of mossy stone brick - just the one, so it gets bundled in with all the other stone variants.

So, I have no desire to disable mossy cobble via config: thats exactly right.

How does this look?

Chisel is "relatively small" and it does add one new stone type (marble) and also the special craftable blocks (factory, armor plating, temple)
Chisel seems a good idea

Enhanced Biomes adds some really pretty stones, especially the chert. You can disable biomes it adds if you do not want them also, and just have the stones generate in pockets.

I had a lot of fun with metallurgy and its metal bricks in 1.4.7. I changed the textures for them by borrowing from a few texture packs though. A practice I heartily recommend. But if you play on servers and want others to see what you see then maybe not...
