I had to revisit the picture. Didn't see any heavy stone or concrete.
Give it a try.
Thanks for pointing that out, I guess I didn't explain my train of thought at all.. A core drill doesn't have any shock or vibration to split the stone, or break the mortar bond between the stone/brick, brick/brick, nor does it care if you are drilling on an edge of brick. It won't slip off the edge.
