Lingering Litany

[Avoron]

The Generation focused arcane school's Lingering Evocation ability looks like it could combine excellently with the spell Litany of Righteousness. Problem is, that spell appears only on the paladin and inquisitor spell lists.

Is there any way to combine these effectively into a single build? Maybe by getting Litany of Righteousness on the wizard spell list, or by getting an arcane school on a divine caster?
