Contrary to the reputation, Fate/GO doesn't actually genderbend that many characters anymore, especially outside of Japan and China. Post Solomon, not counting variants of existing servants:

Gareth (I'm guessing she was already described in the nasuverse)
Sima Yi (Really just Reines with support skills)
Kagetora
Koto Danzou
Hokusai
Nezha
Paul Bunyan
Musashi

They're reaching a bit harder to find waifus. I'm pretty sure most lists of heroes and antiheroes of legend would have Roland a bit higher than Abigail Williams or Anastasia. But it's not as rampant as the memes suggest.
