Scepter of Shifting Sands Transmog

So I’ve completed this questline on my shaman, I have the Onyx Embedded Leggings, Fang of Korialstrasz, and Shadowsong’s Sorrow transmogs, I am however missing a few transmogs. The transmogs I’m missing are

Drudge Boots (Green Scepter Shard/The Champion Returns Quest)
Gnomish Turban of Psychic Might (Blue Scepter Shard/The Only Prescription)
Darkwater Robes (The Good News and the Bad News)
Ravencrest’s Legacy (Treasure of the Timeless One)
Shadowsong’s Sorrow (Treasure of the Timeless One)

I’m also missing my Recipe: Dirge’s Kickin’ Chimaerok Chops, but I DOUBT I’ll ever have that item restored. But is getting the transmogs back possible?
