I would skip on the Tang. Just get one Hawkfish and 2 Maroons. These fish all get around 5" and will fill 46g's pretty quickly. Maybe a blenny down the road, just to add something to the lower levels of your tank. The clowns will probably swim all over and the hawk will mostly perch on LR, so a blenny could have the substrate to avoid conflict.
I too was thinking 2 Maroons, 1 Hawk, no tang, no damsels (unless you want to cycle w/ one, trade it in later), add a shrimp or two, and 1 (pick) blenny/goby/gramma/jawfish, maybe a pistol shrimp if you get the right goby and have your LR secure on the bottom of tank.
