How about applying a little bit of that Luck code to giving some bonus tiles out when you terraform a planet?
10% Lucky - 10% chance of a nice little research / industrial / etc etc bonus.
Or reverse it even - hahaha - "While one of your robotic farmers was upgrading the sald ponds an ancient fault was detected that reversed a major river and "10%" of your planets tiles have subsided!
