Well, yes, that could be made to work.  Pretty ugly tho (sorry Kireeti 
;-).

Again, I'm happy to make the tradeoff of less work for less optimality.
If I'm that concerned about optimality, then I'll do offline computation
and static configuration.  Or human intervention.  I'm not interested in
spending the rest of my life debugging an incredibly complex solution 
that
gives me the last 0.0001% of optimality.
