I see two issues you'll need to deal with.
One is will there be a way to hook up those nozzles to your gargoyles? Generally those spitter things come with their own outlet nozzles built it. Sometimes they may have a "jet" type nozzle, but very often it is simply a straight pipe.
The other issue is the rated head of the pump. Some pumps are designed for max gph flow rate at very low head ratings. The head is basically the outlet pressure rating at which the pump is designed to work which relates to how high it can pump the water. You should be more concerned with the head rating of the pump then the gph flow rate since you'll need good pressure to force the water through a restricted nozzle to get it to shoot a long distance.
With that in mind I don't now if that Little Giant 5500 that has a 2" outflow would be the pump that would work for you. Look at the charts on the link that Meyers posted, you see the flow rates are much lower than 5500 gph (91 gpm), it is the head ratings that are important to obtain the distance through those jet nozzles.
