Ultraworld,
Your main idea of letting trade play a more important role, I really like.
Trade everything, but at a price, trade over a distance: pay the transportation costs. No road? very high costs.
Trade could also play a role in the growth of cities, enough food is just a condition for the growth, not the cause of the growth itself. It may be that growth by food is a basic one in civ which may not be changed.
