Yeah, Rose of Versailles definitely came to mind, but doesn't literally have Jeanne d'Arc as a character (AFAIK) so I didn't theorize about it.
That said FGO features the Chevalier d'Eon too and there's obviously a healthy heaping of Oscar in that character design, although also a healthy heaping of moeblob.
Probably some Oscar in the original Saber too, who lead to all these other blondies.
