Could definitely be interested in this. Would an animistic "Nature" plane inhabited by spirits (of the totemic variety) be an acceptable Plane for a faction to draw from?

Indeed. The Planes have now been designed, and you sound like you'd be interested in Fél Válásí, The Eternal Verdance. It's essentially a sprawling jungle that stretches further than any mortal forest could; considered wholly evil by some, and simply nightmarish to others, it has the potential to host a myriad of demonic beasts that draw inspiration from the more natural aspects of beasts.
