I quickly put together an item set for you,
ItemSet 302407
Basically this emphasizes on evasion, but still allows you to be able to have some sort of hitrate on Maat.
Obviously the Kabutowari +1's are unnecessary, you can go with the NQ. I'd suggest going to level 70 if possible, so he can use dual Fudo's (And potentially Optical Hat if you want to put the effort into getting him that)
Some of the pieces are a bit pricey (Elusive Earrings, Scorp +1) but you can go with a lesser value for those. Only use the Ninja Hakama if you're fighting him at night, otherwise Ryl. Kngt. Breeches will suffice.
You'll probably want to put together a Jin setup. Honestly most of that gear you can use for Jin as well. Big changes would be Body->Haubergeon, Legs->Ryl. Kngt. Breeches, Feet->RSE2(dependant on race)/Leaping Boots/Rutter Sabatons, Waist->Life Belt or similar, Neck->Chivalrous or similar, Earrings->Attack options.
Good luck!
