Sorry I deleted my prior post, I was hoping it would be before you read it. I realized I was erroneous in what I said. What you want to do is open the luddic_church.faction file in Ship and Weapon Pack, add a line under hullFrequency for the Cathedral, and give it a weight that is above 1 and keep trying different figures until you get a number of them that you are happy with using that mod list.
