I am not confident in the approach because all structures provide guides holding internal gravitiational effects which are way more significant than we anticipate and can be modified directly.
I do expect that all this will respond to much simpler mathematical modaling when we get down to it. After all the ancients depended on the mathematics of ratios to learn a lot and gravity itself is deeply geometry dependent. Intuiting ratio and resonance allows progress.
Gravity is not always attractive. Can you think of a citation to an easy-reader explanation for a layman ?
