I have sought guidance from Thang Tong Gyalpo and I have another approach for you.

Thangtong Gyalpo (Tibetan: ཐང་སྟོང་རྒྱལ་པོ་, Wylie: thang stong rgyal po) (1385 CE–1464 CE1 or 1361 CE–1485 CE[2]), also known as Chakzampa, the "Iron Bridge Maker"... and the King of the Empty Plain. He was a great Buddhist adept, a Chöd master,[5] yogi, physician, blacksmith, architect, and a pioneering civil engineer. Thangtong Gyalpo is said to have built 58 iron chain suspension bridges around Tibet and Bhutan, several of which are still in use today. He also designed and built several large stupas of unusual design including the great Kumbum at Chung Riwoche...
The horizontal rectangles are stone. They are moored by chains each of which areis anchored in a stupa on the cliff. Between the stones are planks of wood as shock absorbers so the stones do not rattle against each other. I am sorry I could not make 3d chains that faded into the background; imagine those black triangles as chains.
Stone is strong in compression, weak in tension. The stones here are essentially stacked on top of each other, their weight being transmitted in part through the anchor chains and in part compressing the stone behind it.
The benefit of this is that it is fantastic yet plausible. A great web of blessed chains extends back from the bridge to nowhere, with the anchor to each in its stupa guarded by three statues.
The best thing about this idea is finding out about Thang Tong Gyalpo, who really did use iron chains to make bridges that have lasted 500 years. I like the combination of Chod master and civil engineer. Not all Renaissance men were from Europe!
