I don't know if that would be possible, but here it goes nonetheless.

Carpenter's Cylinder, a cylinder like piece of block. Each block would look like a barrel, and could be used vertically or horizontally. It could be used to construct columns/pillars, realistic piping, barrels etc.

And for the extra mile, it could have variants such as 90 degree turns, T-intersections, 5 way intersections and 6 way intersections. The cylinder diameter could also be configurable to make thick or thin piping/pillars.

Another variation could be half-cylinder or quarter-cylinder so you can make smooth, rounded wall ends, or wall corners.

I'm not sure how square textures would wrap around circular object coordinates, but I trust there could be some generic catch-all ways for that. Some might look ugly for intricate textures, but I trust for plain looking textures it would be alright.

Round Carpenter's objects? That's model territory (aka a different mod).
