Polished/Cut versions of Material Blocks

We've gotten Polished Granite, Diorite, Andesite, and Basalt blocks and cut Copper blocks. With this next update being, as Agnes put it "making Minecraft Minecraftier" I think a good way to stick to that is giving Iron, Lapis, Gold, Emerald, and Diamond blocks extra variants. While (most) of the [material] Blocks look fine, adding cut or polished versions would be a nice thing to see, and even make them look better though at the cost of the materials which is a fair trade off in my humble opinion. I doubt this will get any attention but they're my funny little thoughts!
