I have thought for a while that L. Ron Hubbard would make a surprisingly good Caster. He actually dabbled in occultism with a disciple of Aleister Crowley, his official biographies present him as being meeting a bunch of old magical types like Blackfeet medicine men and Buddhist lamas, and it is easy to spin Scientology as a deliberate effort to be immortalized as a Heroic Spirit that is masqueraded as shameless money-grubbing to deflect magical attention.
As for older figures, a Freischütz would make a fine Archer, and probably one of the few mythological or folkloric gun-wielders that doesn't come straight from the American frontier. Obvious Noble Phantasm is the Freikugeln, which would have an interesting dynamic with the seven-participant model of the Grail War, too, since it rations him to one Freikugel per enemy Servant, and if he goes over that his seventh bullet probably does something like kill his Master.
Doctor Faustus is another candidate for Caster.
Lee Harvey Oswald as Assassin comes with a clear Noble Phantasm: "Magic Bullet".
