Capital Blocks in both Wood and Stone Variants

We need variations of capital blocks (the decorative top block on pillars and columns) in both wood and stone variants. You can make some unique ones utilizing stairs and slabs but they are 1) Not really very ornate and 2) Force the build to become far wider to make any sort of detailed ones where sometimes the width of the column needs to be a single block. Capital block variants would add tons of creative possibilities for castles, bridges, houses ...basically any structure you want to build in the game.
