I don't think there is an 'easy' way to kitbash these.
Closest I can think is to make an Autarch with Swooping Hawk animations and make that overhead shoulderplate thing like it was made for Necron Immortal/Deathmarks. You'd still have to alter the armor to have those fronal exhausts on the shoulders and model the jetpacks from behind. Rifle and clothes would have to be modeled as well.
Shadow spectres are awesome!
oO Oo

They're a bit of a nightmare.
