This seems like a bad comparison to me. Yahweh was a classical storm god, but comparatively little of Yahweh's career as a local storm god (especially in regards to being a member of a pantheon, Yahweh certainly was, and even had a wife, but compared to Odin, Zeus and a later example, this part of his divine life is a bit bare) remains and even in the educated mind his later myths hang over his old identity. Meanwhile, Indra fits the bill FAR better, being unusual already to western layman's ear, but having a far richer (and more accurate to Orlanth's own journeys and stories) tapestry of myth to pull from.
