I doubt it would work well on Kirin, because other than the negative correlation, Kirin has a straight 50% damage reduction from any element except wind.

Morgana's Choker above 50% MP.
I believe this is the best possible setup disregarding Novio Earring and random augmented items.
Maat's Cap/Yigit Gages/Mahatma Hpl./Morri Legs/Morri Feet should be very close to Morrigan's Set in terms of raw damage, not sure about m.acc though.
Spells were:
Regurgitation (1 SP, +1 INT +1 MND, core spell)
Power Attack (1 SP, +1 MND)
Sprout Smack (2 SP, +1 MND)
Cursed Sphere (2 SP, +2 MND)
Poison Breath (1 SP, +1 MND)
Grand Slam (2 SP, +1 INT)
Chaotic Eye (2 SP, Conserve MP combo)
Venom Shell (3 SP, +2 MND)
Awful Eye (2 SP, +1 MND)
Bad Breath (5 SP, +2 INT +2 MND)
Hydro Shot (3 SP, +2 MND)
Zephyr Mantle (2 SP, Conserve MP combo)
Mandibular Bite (2 SP, +1 INT)
Tail Slap (4 SP, +2 MND)
Actinic Burst (4 SP, Auto-refersh combo)
Reactor Cool (5 SP, +3 INT +3 MND)
Magic Hammer (4 SP, +2 MND, useful to have)
Plasma Charge (5 SP, Auto-refresh combo)
This with capped Assimilation merits.
I think this is the best possible spell setup if you plan to
only cast Regurgitation to keep your enmity low.
Magic Hammer is there if you think you can pull it off, Conserve MP and Auto-Refresh are pretty much mandatory.
Magic Fruit and Metallic Body aren't a necessity since you should sub RDM and with all that MND capping Stoneskin is a joke.
If enmity is not an issue you can drop a few stats-only spells and add Mind Blast, Firespit, Memento Mori and Amplification in the mix but be careful as pulling hate cycling through those spells is very easy.
