I think it's an excellent idea to make the cage 6 feet again – they will enjoy the space. I have three four-level, 6 foot cages (one with 6 females, one with 5 females and one with 5 males). I clean them one level at a time over the course of a week, not all on the same day, and I have no problem with my goos.
You have a good selection of items in their cage to keep them happy. I also have at least one hut in each cage as well and pumice stones. Check out some of the dedicated degu forums like the Degu and Chinchilla World Forum or Degutopia for cage accessories ideas.
