Deepslate generation and use in other cobble recipes

As Deepslate was added as an equivalent of cobblestone, and most of it's uses are on par with cobblestone in crafting recipes (stone tools, brewing stand, furnace, etc.), it should also function as a use in all of the recipes cobblestone can be used, which the remainder of mainly compose of redstone components, such as the observer, piston, and dropper/ dispenser.

Blackstone also has this issue.

Deepslate should also have the ability of basalt, which is renewable and can be generated in the way cobblestone can, with soul soil included, whereas the only current way of aquiring large amounts of deepslate for building are strictly through mining.

The included block is subject to choice, but I propose Deepslate should be generated in an equivalent method as basalt, but instead of soul soil, it uses Blackstone(as it is a darker form of stone), Obsidian(because it is a stronger form of stone), or possibly even amethyst blocks, giving them another use over the aesthetic sound, and suggesting that deepslate is a stone/ amethyst mixture.
