Yes you can. Wrasses, groupers, snappers, lion fish, squirrel and eel are safe will zoo's. The more aggressive Triggers may bit into them but there is a group of reef safe Triggers that would be fine. A lot of the larger Angel do eat zoo's so they're a crap shot. So there are quite a bunch of fish that will be fine with zoo's.
You do need to take into account the additional load place on the tank as that will increase nitrates which aren't good for zoo's or corals.
