The A380 could be saved by an increasing demand for freight traffic.
The aircraft was designed to be a freighter as a new build aircraft (A380-800F), thus it would not be surprising that designs for retro modification of passenger aircraft are readily available.
Modification of a slightly older generation aircraft could be easier that cutting into more recent 'plastic' aircraft.
Also the double deck 380 could have advantages in multiple side loading doors and possibly for nose lift, although the latter might not be required or viable.
