Interesting idea. I agree with the other poster that 4-6 seem off, but I'd add that 7-9 also seem off.
Maybe the below works better. It also has an order to it. The second set ruled by Neptune begins with sustaining, and the third set ruled by Pluto begins with destruction.
4 - Sustaining aspect of sustaining (stability)
5 - Destructive aspect of sustaining (sustaining is impossible- something has to change)
6 - Creative aspect of sustaining (utmost worldly fulfillment)
7 - Destructive aspect of destroying (Termination, Ends, Limitations)
8 - Creative aspect of destroying (you have to "work" it, it's not stagnant)
9 - Sustaining aspect of destroying (sustaining something you already found at 8)
Its not quite that way, but close, how it is is:
1 - creative aspect of creation
2 - sustaining aspect of creation
3 - destructive aspect of creation
4 - Sustaining aspect of sustaining (establishing frameworks)
5 - Destructive aspect of sustaining (adaptation)
6 - Creative aspect of sustaining
7 - destrucgtive aspect of destroying
8 - Creative aspect of aspect of destroying
9 - Sustaining aspect of destroying
Exactly, it follows the same concept
