The only concern with you fish and coral is naturally the Angel. They are know to be coral nippers and may be a problem with any additions of coral you make.
That said in addition to what you already have I would look into some Euphyllia. Especially the torch Euphyllia glabrescens or a frogspawn Euphyllia divisa. To me these are some of the easier of the LPS to keep and will give your tank some added movement with their swaying in the current.
Next I would think a fox coral Nemanzophyllia turbida, or a candy cane Caulastrea furcata.
