chimney cap question

OK, so I just finished repointing my brick chimney, all new copper flashing.

Previously it just had beveled mortar on the top of the chimney, with the flu sticking up a few inches. I wanted to add a cap.

So I laid up 5 half bricks on each corner to get about 9-10" of clearance between top of flu and bottom of cap (will be bluestone).

What I'm wondering is, I've never really laid brick before. These 5 bricks in the corner look like I could blow on them and they'd fall down. But maybe after the mortar cures they'll be OK? I see this design all over town, I'm just not very confident in it and I don't want bricks and a huge piece of bluestone tumbling down my roof, which is steep and high with streets on two sides of the house.

So, assuming I mixed the mortar properly and laid the bricks properly, is this going to stay put?

Should the stone be mortared to the brick, construction adhesive, or what?

If you still have flue sticking up just do this in your size, easier and will keep the critters out.
