What’s the difference between the 2004 and 2006 versions? Or do you mean the 2006 bonus discs with the theatrical cuts? If so, you already included Despecialized, so why bother?
Anyways, you always want to put three movies on a single disc, that seems a bit much to me. You might get away with putting the 3 DVD versions on a single bluray, but 6 hours of 4K video on disc thirteen seems totally unrealistic.
