Alternative goods contracts

Contracts are amazing way into mid/late game, allowing you to skip some production chains and make your gameplay more unique.
It would be great to have more variety of contracts, perhaps even randomized or custom based on your settlement parameters.
E.g. reaching health value of +40 allows you to trade medical 3 -> gold. Or reaching unity reserve of 500 gives you luxury goods->gold.
This would be a new mechanic to nudge players into setting late game goals other than terraforming or reaching pop size.
