Matt,
On my last trip Down Unda, I started with a fat-bike box, which was 10" wide and 32" high. (I had to cut that down so that it was 38" long, so that it fitted within the 80" total linear dimensions allowed on my flight.)
If you can get a 32" high box, that might save you the hassle of removing and then refitting the forks.
If not, then George's suggestion makes very good sense. The exploded diagram of the FSA headset is valuable -- when reassembling my forks, the lower bearing cage went walkabout across the garage floor, and I wondered, "Which way up did it go?" Corollary 93B of Murphy's Law dictated that the 50% chance worked against me, and it took a bit of fiddling and close reading of the FSA diagram to get it right.
Good luck in any case. Look forward to your tales of Morocco.
Safe journey/safari njema (as they say in East Africa),
John
