What would you do differently if you woke up as Quellon Greyjoy [Spoilers Extended]

Did a similar post before with Aegon V and i liked the answers. Let's assume you have future knowledge on the Greyjoy Rebellion after your death and overall know what your surviving sons will turn into. What are you doing about your sons, how ensure your house prosper in the next generation and how would you go about plans to reform the ironborn culture?
