Well it would be useless, that's the problem.  The value of happiness is 
to allow more people to work.  To estimate the effect of them working 
you'd need to estimate F/S/T obtained through their (best) placement.  AI 
can do it poorly for itself, CMA can do it perfectly for the human.

The only difference is that in "my" case you know the CMA weights.  
So the solution for SMA would be (also user-supplied) default CMA 
settings.  Sort of "what do you want from your next city?"  "I want a lot 
of trade and just enough food and production".
