My 2 cents
Basic elements: Time+Aether, without them nothing is possible
Interaction elements: Gravity+Entropy+Fire, necessary for other to interact
Matter elements: Earth+Water+Air, the basis of the material universe
Existence elements: Life+Death, the name is self explanatory, i think
Spiritual elements: Light+Darkness, i know, Light could be under interaction and Darkness is more an "idea" of something, not a true element
How i see the order:
Basic is above all others, Interaction+Matter=Existence, Existence-->Spiritual
Just my idea
