Plan on the A380 not returning, offer VR on generous terms to those that want it. Most of the pilots would be reasonably senior and qualify for a decent package.
Try and absorb the remainder back onto other fleets or ground jobs. Those in flying positions would remain current and could be bought back onto the A380 relatively easily IF it ever comes back.
Realistically, it will be 3 - 4 years before it would be a reasonable proposition to return the aircraft to service at all, let alone expect a decent amount of profit.
The ME 3 have a huge worldwide network and can slot an A380 onto a route as soon as the traffic justifies it, QF have a handful of A380 routes most of which are still badly affected by COVID with no end in sight. Even with possible travel bubbles to SIN and HKG, you’d struggle to fill a B787/A330 at the start.
