I totally agree with Mr X. I think that having multiple Triggers is begging for aggression issues at some point and the overall list has a lot of messy eaters that will push filtration.
I think the Porc might be okay, but I'd go with a larger one if you had to have one.
I think a decent sized (not juvenile) Harlequin Tusk would be good. I agree with the non-reef safe wrasses as cool additions. I'd get another Tang and maybe some kind of Foxface/ Rabbitfish. All would hold their own in there.
Groupers are cool, but they do get huge and they do so relatively fast. I inherited one about a year ago that was over a foot long and promptly handed it over to a LFS
because my 240 was just too small.
