For places like Mor Dhona, Idyllshire and Doma where they're in a constant state of rebuilding, they could add an NPC that takes gil donations to help with the "rebuilding". A list of top 20 donors get listed on a board and every month the largest donor gets a giant statue of himself in the town square. Not sure how difficult that would be but the statue can be an up-scaled static model of the donor in whatever gear they were in at cut-off time. people could come up with weird and funny combinations for the town statues.
