Springeri Dottyback? If you add him last shouldn't be too bad, plus get some great color and activity. Another option yellow assessor?
Pseudochromis sankeyi (striped dottyback) seems to be an active fish, and you could add a few of them, as long as it's at the same time. If you're not against hybrid fish, the indigo dottyback seems to be another fish that's active and can be added in groups.
Apogon compressus (ochre striped cardinal fish) is another schooling fish, but they do seem to be more active in the evening/night.
Ptereleotris zebra (zebra dartfish) also do well in schools, but they do need a sandbed and can be jumpers.
Bi color Dotties are cheap and spunky. Chalk bass are mellw and hardy. They shoal and have a subdued beauty. Maybe local for the comon cheapies? Order some of the money wrasse online w a 14 guarantee?
your list is great but im just a tad concerned with the labouti as they can be very skiddish and hurt themselves bouncing around in the tank when people walk by
