Thanks for the suggestion. The only problem is that when the Rebels take it, they'll then inherit the problem, which spoils the asymmetry. I might use the credits accummulation factor (please don't tell me that's disabled too!) in factions.xml to give the Empire a lower rate, which I'm assuming means it gets a lower income for a planet than if the Rebels occupied it.
