Ores inside Sulfur and Cinnabar

After playing around a little bit with the new Sulfur Caves, I noticed that, since a large portion of the walls is covered in Sulfur and Cinnabar blocks, common ores are unable to spawn there. This gravely decreases the usefulness of the new caves, limiting the resources that are available. I suggest that ore variants of Sulfur and Cinnabar blocks be added (e.g. Sulfur Coal Ore, Cinnabar Iron Ore), regardless of how realistic it would be, in order for ores to be able to spawn in the new caves.
