Isn't M'naago's gear just the level 60 Fillibuster gear from Baelsar's Wall though? (At least, that's what she appeared to be wearing during her original appearences at the end of
Heavensward and throughout
Stormblood, which most of the Ala Mhigan Resistance wear to be honest).
I admit I'm not a crafter though and so I don't do Custom Deliveries, so if she wears something else disregard this.
EDIT: FF Wiki also has an
image of her wearing what appears to be a generic pre-level 50 harness and padded pants, which is easily crafted or gained cheaply from npc vendors so yeah, if that is the case it's easy to glamour her if you want already.
