Would this be a good idea for a fan mission? An entirely different take on the game from a historical perspective of the Precursors.

The quakes that destroyed Karath-Din would be retconned to make it into an ancient precursor conspiracy. You'd play as an industrial regulations official under the command of the fair and loved Emperor Va-Taraq, and you'd be investigating the development of new agricultural technologies, namely a certain chemical and atmospheric devices and their connection to one another.
The emperor dies, presumably of natural causes, and his incompetent son Va-Toran comes to power. Your department is not happy about the way the heir runs the nation, and suspicions of corruption begin to surface. Your clues become dead ends as important people begin to disappear. Eventually spooks clad in hooded cloaks come after you too. This only gives your investigation the push of extra motivation it needs.
The remaining clues you're investigating take you to the ransacked apartment of a crazy conspiracy theorist. He has died in a staged suicide. You find a secret room with a makeshift laboratory. You find the test results of a chemical experiment he did using a gaseous substance and a device inside a glass cage.
Your revelation comes too late. The lack of regulation in the agricultural alchemy industry has ended up approving the simultaneous application of the Necrotic Mutox weed killer, and the Carbodioxidic Cultivator device. When combined, the chemical becomes a self-replicating oxidant that consumes everything biological in its path.
Your final sacrifice takes you to the national terramancers' geothermal power distribution complex, where you must trigger a seismic chain reaction to bury the doomed city in order to save the rest of the world from a rusty demise. Karath-Din sinks under the rock along with you, with all traces of living beings completely annihilated by the rust gas dragged down with everything else.
