I made this pack because I thought that the stone variants(granite, diorite and andesite) needed more variants. I also really like the tiles form deepslate. So I put the 2 together and this is the outcome. This modifies the double slab variants.

Granite Double Slabs = Cracked Polished Granite Tiles
Andesite Double Slabs = Cracked Polished Andesite Tiles
Diorite Double Slabs = Cracked Polished Diorite Tiles

Polished Granite Double Slabs = Polished Granite Tiles
Polished Andesite Double Slabs = Polished Andesite Tiles
Polished Diorite Double Slabs = Polished Diorite Tiles
