More building choices

I had an idea for Minecraft:give the player more building blocks, everyone different than another;I was building a sort of Ancient City like Rome when then I noticed that Minecraft doesn't have the blocks that I can use to make the Pantheon, why not add blocks like stone, Andesite or any other material pillars? Or even blocks like concrete (Roman concrete or concrete that looks more like the one used in real life to make houses in Europe), hope Mojang will read this Suggestion! i hope I said every word right even though I'm bilingual (since I'm Italian-English) and sometimes I forget some words in English.
