I mean, such a tiny population is very hard, and I'm not sure it necessarily counts as a "screw", but I've always wondered about reversing the roles of the Jews and Samaritans, leaving the Jews in Samaria ("Judea", I guess) while the Samaritans spread out into a global diaspora. Honestly, it makes way more sense, anyway, considering how absurdly centralized Judaism was at the time of the Temple, compared to the looser style of Samaritanism.
