Bricklaying & Repointing

Block "Pillar"/parapets on top of wall

Hi, I have built a breeze block garden wall with the blocks laid flat. The wall will be rendered. I want to put a fence topper on top of this wall. I think that building small block/brick pillars on top of the wall every ~1.8m and securing the fencing to these would look better than using metal brackets to install vertical wood fencing posts on top of the wall at 1.8m intervals. I would, in effect, be creating a parapet with blocks and putting fence panels between. The pillars would only be ~0.4m high (inline with fence topper height). The pillars would also then be a great place to install some lights. The pillars would ideally be square/cuboid lxdxh (215x215x400) on top of the breeze block wall (as previously mentioned it has been built with blocks laid flat.) What is the best way to build these pillars/parapets? I figure I have several options. a) the easiest - lay 2 breeze blocks standing on their smallest face creating the cuboid. Can this be done/would it be stable enough? Ina way the fence toppers would then be providing additional support. b) break 4 blocks into 215x 215 size and lay them flat. How would I then get a flat surface on all sides to render? c) to solve the flat surface issue I would break blocks into 215x100 and lay similar d) use bricks I would have to buy bricks as I don't currently have any but do have left over breeze blocks. Thanks in advance!
