Add missing blocks of deepslate and stone

It would be very cool, if you would complete the Stone and Deepslate Variants.

What does that mean?
At the moment, Deepslate has Specials and Stone has Specials. For Deepslate these are the Tiles (Deepslate Tiles and Cracked deepslate Tiles) and the reinforced deepslate. For stone this just would be the mossy stone brick and the craacked version of it
It would be very cool, if you add mossy deepslate bricks in uncracked and cracked, so that dark and old builds look great and wethered.
On the other site, I think there is need of the Stone tiles and the cracked stone tiles. In my opiion it woud just complete the missing stone variants. 
For reinforced deepslate, I dont see any use to make a stone variation of it.
Thank you
