Well, if you go by some of the "mythology" from the graphic novels, each Clan tends to wear similar armor, so yes, you would have many Preds looking the same (or similar). The movies were not like this. In Predator 2, we see a group of Preds on a hunting trip and most of the armor and all of the helmets were different.Even in K80s images, you can see similarities in the armors.
Worst case scenario, you'll end up having to switch up the armor between the different color pallets of the figures.
