My opinion: you can go for 3 large angels that you originally wanted (french, emperor, blue face) and you can drop a couple of tangs to make room.
If you ultimately feel you do not want an emperor angel, I'd say drop a couple of tangs (1 zebrasoma and the atlantic blue) and get a clown tang instead. Would be a shame if a nice 700 gallon tank did not feature a large bold active fish.
