With a 1 turn = 1 week scale, I would think that a decent shipyard 
could churn out 100 MUCr. of work on any 1 ship (though it could work 
on more than 1 ship concurrently) per week.

Your average CH would take approx. 25-30 weeks to complete, while 
destroyers could be produced at a ship per 3 months or so...

I'm not sure about that. It's still MOST advantageous to have 
everything in one place, and simply makes players juggle the numbers 
to make the elements match.

Likewise, abstract MUCr. makes trade simpler to manage. All you have 
to do to encourage trade is to make income and production facilities 
unequal. For example: a system with shipyards will almost certainly 
need to import MUCr. in order to keep production at max capacity. 
OTOH, a core system with high income and little production will, by 
necessity, need to export MUCr.
