As David points out there is not a one-to-one correlation to the porfolios of the POM and the nodes of the tree of life. But they are close enough to make some obvious placement connections. I used the process of elimination for the rest. I don't think we are ever going to find an exact match as I don't think Uncle Henry would simply copy a pre existing world view. He seams to like to challenge expectations and "tinker" with existing preconcieved notions.

Regardless I think we can all agree that the Arcanis Pantheon incorporates a vast number of conflicting world views, just as it incorporates a vast number of cultures. The Tree of Life spans at least 6,000 years of human history, and crosses across the majority of cultures while at the same time being a cult object of speculation. As in Arcanis the Tree of Life is said to have absorbed a simplier world view of Fire-Water-Air-Earth.

The BIG inferance from the Tree of Life Annonology is that we could spend several life times of effort trying to unravel the relationships between the POM and still have questions. Laying the ground work for that sort of Mystery makes for good writing.
