Sedum or similar

Question

Is there a variety of sedum or similar, that can be just scattered between the crevices of a brick wall. I think they look so attractive and change the look of the top face of an ugly,bare brick wall.The seeds are so teeny and there is not a great deal of space to add compost. I notice that one side of the wall, along the top has seeded itself into the crevices. Perhaps by birds or wind. They are bright yellow flower heads on bright green tendrils and are spreading. I have a packet of Aubrieta, cheeky mix. What do you think of this idea? and is it possible?

Can you include a photo of the area in question? This can help me to determine the best solution for the area.
