I know agile and scrum and so on carry a lot of baggage these days but what you're describing is Less Agile. You flatten the org back out, create product teams that pull from a single common backlog and developers interface directly with their customers. That's not even the most controversial part! You also do away with pay tied to individual goals: everyone succeeds or fails together and are paid the same way.
