James, I went back and re-read your post and again I couldn't find anything
that makes Yesod as successor to Briah as untenable. Perhaps you can explain?
 
For, example the bit about vantage point, looking both forward and back. I don't 
see the need for leapfrogging universes.  
 
As I see it the Hiero race created Hierogrammates but perished in the destruction of
Briah. Hierogrammates were able to escape to the next universe, Yesod.
 
They are parked at the beginning of Yesod. Hence Severian doesn't have to travel
far to reach the Yesod planet. With this "machine planet" Hierogrammates are in the 
process of constructing the future planets of Yesod, including, eventually, Earth (not Urth).
 
Thus from this early Yesod vantage point they are able both to work forward to construct the 
future of Yesod and send agents back to Briah to ensure their own creation.

Does this work?
