I think you have a couple of options:
If you intend going to Morocco or indeed Spain or Portugal some time after this Morocco trip you could always park the jeep up somewhere in MA or Spain so you can save a few days again on the next trip.

As regards driving it down and back you could find someone but between ferry, flight, fuel and other costs it might be a bit expensive. I would personally be very wary of driving someones car back from Morocco but see how you go. Either way it is much easier from a bureaucratic point to get someone to drive the car to southern Spain, and not Morocco, same goes for picking it up.

If you intend to ship you can try ro-ro, there are plenty of options on this such as Grimaldi, or try a container shipper such as Maersk (a 6m will do you), or a forwarding agent such as Kuhne & Nagel.

The cute hoor in me says get registered with the AA, get their Euro cover, see if they ship a broken Landcruiser from southern Spain to Dublin or Rosslare, "break" the Landcruiser and have it potentially shipped back for free.

Note I said potentially. i.e it probably won't work.

Btw two drivers will easily do Cherbourg-Algeciras in 24 hours in a half decent car. I did it on my own in old Merc vans in 40 hours a couple of times. So maybe finding someone to take it to somewhere in France or northern Spain would be an idea too.

You also need to find out if the insurance company will take that person on the Landcruiser for the few days.
