Please keep us posted because there are other folks that would benefit from your local plant info!! I can't remember if you asked about sources for plants - I use Aridlands.com they are so nice and get the plants out really quickly, and the plants are exactly what you expect! I have purchased several cactus and tender succulents from them!!
I would imagine that sedum repestre - either Angelina or any of the other types, would do well for you there, just keep them from afternoon sun
