yeah. Xenia's, Kenya's, star poyps, etc.. lots of softies. You could proabably do some sps too like trumpets and candy canes. your averaging 6watts per gallon so I'd say your pretty good to go.
As long as you have the lights only about 2 or 3 inches above the surface, you can keep anything you want. some super highlight SPS might not do well but the vast majority will, especially if you are putting them in the top half. Flow, water chemistry and stability are equally as importaant factors however.
