Answer: I'd try trailing Sedums in baskets, or Sunrose, Lantana, Rosemary, Creeping Thyme, Gaillardia, Linum, Salvia or Russian Sage. The reflected heat and light complicates the problem of droughty conditions in hanging baskets with the exposure you describe. Try watering twice each day during the hottest summer months to refresh the plants and keep the roots from overheating. You might also try planting in pots and placing the pots in the hanging baskets, surrounding them with additional potting mix or sphagnum moss to act as insulation against the hot sun. Hope these suggestions help!
