Wanting To Change Husk Spawning Conditions

I've made a post similar to this earlier, however, I wanted to keep this all in one place here. I want to change how Husks spawn on the SMP I play on. One of the solutions I came up with is changing the fact that husks can spawn in desert pyramids, the problem is that I never noticed how small desert pyramids really were, so even though it is still an option I think I want to do something better. Just allowing Husks to spawn in the desert no matter what, as in Husks can spawn in if there are blocks above it and if the block isn't sand. I have already figured out how to make them drop sand, but I would like change this other feature. Please provide guidance in this matter; I know this is a significant request. Thank you so much for all the help I've received and will receive.
