Just to be clear you're talking about something like this? Then I agree with Eric, making them in 3D seems like it will give you the most control and best results. Plus you can sculpt in some great details if you need to. I would start off with a row of instanced bricks (so you can make changes to them all by only editing…
It depends on what type of bricks/pavers you use. If you use square bricks you get a big gap at the outer ring and they touch at the inner part. If he's willing to warp bricks with polar coordinates then I don't think wedge shaped bricks are all that bad... Cut to fit or custom brick shapes are pretty common and in a lot…
