Alright, after playing around with it a lot, this is what I came up with:
I took the 7 traditional planets, and split them into Yin and Yang, negative and positive, for a total of 14.
Sol
+Anima (life-giving force, collusion, order)
-Fire (includes Magma)
Luna
+Mind (Zen, Psionic, opposite to Spirit, intuitive)
-Water (includes Steam and Ice)
Mercury
+Sound
-Air (includes Wind, swiftness, rapid movement, agility)
Venus
+Charm (Magical force, purely emotional, feminine, opposite to Destruction)
-Poison
Gaia
+Natura (wild nature, growth, plants, includes Wood)
-Earth (the nurturer, stable, does not include metallic minerals, does include crystals)
Mars
+Vigor (enhancements, courage, Willpower, etc...)
-Destruction (Physical Force, negative Vigor manifest, masculine, opposite to Charm)
Jupiter
+Lightning
-Metal (the protector, a more powerful Earth, includes all Metallic Minerals, and Magnetic forces)
Saturn
+Spirit (Opposite to Mind, Etheric, ritualistic)
-Chaos (life-taking force, expansion, disorder)
