Sure, the "nemo's (ocellaris) would be fine. If you get a royal gramma I would either go with a possum wrasse or find another fish in place of it, perhaps 3-5 Sunburst anthias (behave like hawkfish, perching on rocks and upside down under ledges at times)...so maybe:
x1 yellowhead jawfish (most common)
x3-5 Sunburst anthia
x4 Pajama cardinals
x2 ocellaris "nemo" or percula clownfish
x1 royal gramma
x1 flame angelfish (if you feel you have adequate space when all said and done)
