With that rule, an explainable reason for why there is five people is most likely because someone among them is Limited SSR, just like Scathach on EPU or King Hassan and Merlin in Babylonia.

Costume change is another possibility, however I don't remember some available Servants with silhouettes resemble them (except Raikou and Shuten).
