It would take alot of ambition and forethought from whoever attempts this. Such a cultural movement would have to take place well before the Viking Era. Probably even before the Frakish King Clovis' conversion to Christianity. Apart from Runic inscriptions, literacy was not high among the Germanic-Norse tribes cultural achievements, so Christian priests and monks filled out their niche in Germanic tribal society as bureaucrats and scribes, and made themselves indispensible to the likes of Clovis.
A codified written tome of scripture and/or a politically influential priestly order are necessary in espousing a definitive religious ideology that could encourage enthusiam. Germanics had their Volvas or shamanic practitioners, and it was frequently clan chiefs whom presided over religious occasions, but they did not possess single extensive corporate hierarchy, like the Christian Church, so they really had a common belief system without an ordained agency to operate it.
One thing worth considering is that before Charlemagne's conquest of Saxony, the tribal centre of Marklo (located within the Hoya district of Lower Saxony) was where annual meetings between the chieftains, re-affirm ancient laws, practice judgements, and decide whether or not warfare for that year was necessary. A new cultural revolution may be noticable if it begins there. It might also serve as a prototype for permanent institutions that could maintain the long-term goals of the nation.
In Norse society, these tribal gatherings were called "Things". The Christian Ecclesia, another name for the Church, is a term borrowed from ancient Greece, which was originally an assembly of the citizen-body when they needed to vote on important issues. So perhaps Germanic tribal assemblies could be the inspiration behind a professional cultic organization.
