Basque In My Glory

Needs Fate of Iberia, and it must happen before the year 1200. The decision is "Champion the Faith of the Country Basques", and it wants 1,000 prestige, 1,000 piety and the right counties - so the wiki simply starts as the counties' owner: replace the King of France in 867 with a custom Basque-culture ruler (Cynical, so the faith swap doesn't sting, plus prestige- and piety-generating traits). Farm the two currencies for a decade or two and take the decision. Euskal Erlijioa lives again.
