I like this idea.

About Berserkers and King Harald : Aside from bear skins, they were also using wolf skins. The arcana on the card presents some kind of wolf-like creature. In popular culture, as we know, a werewolf is symbolic for someone losing its mind under the influence of the moon... The double-meaning this card provides is, in my opinion, quite fitting with Harald I representing the Berserker on the card... He might even be the Grand Berserker in FGO.

As for the others... Aside from the Holy Roman Empire, what do we have when it comes to hat-wearing spearfighters? Not sure about Agrippa... he doesn't strike me as bearded wizard but why not :)? Rider is a charioteer. Who could fit the charioteer motif the best? I found Porphyrius but he is an athlete, not a timeless hero :/
