I would be delighted to take part in this sort of effort. My list of edit ideas has been growing for years. There are definitely some things that need to happen with season 8, and I love that re-cut of Rhaegal’s death. Makes so much more sense. In particular, there’s a lot in-between Dany’s death and the final montage that needs to go. What I’d love to see is a “consistency edit”. For example, things like the Eyrie should look the same in all seasons, rather than undergoing a complete re-design retcon. One of the most jarring changes was Daario, but that would be a major undertaking.
