I've thought about this, and it makes sense. Any argument I could use 
against having a division inside states could also be used to argue 
against a division among states (e.g. why have one from each state? why 
not one from a block of states? Thus you should have one from a region 
of each state if you have more than one).

Districting runs into gerrymandering. I think the solution there is to 
let some independent body do the redistricting -- it works in Canada. 
That raises the question of why such hasn't been done already, but I 
think the parties are just too strong. The initial cancelling-out done 
by Condorcet might be enough to pull the system away from that kind of 

More exotic systems might be possible - for instance, some sort of 
supermajority requirement for councils of two, or a weighted kind of PR 
that pulls the centrists towards the center, or something, but that 
lacks the simplicity of the ideas above.
