Expensive to make, mind you, but da bomb!
The only options to meld to it are:
Vitality -- Enhancement Boost
Mind -- Healing Boost
Piety -- Enfeebling Boost
Fire/Ice/Wind/Earth/Lightning/Water -- Damage boost
Hells' Fist -- Damage Boost
Sagacious Might -- Critical Damage Boost
Battledance -- Parry

As a Healing WHM (where the majority of the time your concern is healing arts, and you are not considering swapping out during attack times), the only really beneficial ones are Vitality and Mind.

If you can add 2x +20 MND (+40 MND) you would get +10 Healing and +10 Accuracy
If you can add 2x +20 VIT (+40 VIT) you would get +10 Enhancement Magic Potency

So your end result would be:
MND +45, Healing Magic Potency +22, Magic Accuracy +20, Magic Evasion +10, Spell Interrupt Resistance +50
OR
MND +5, Healing Magic Potency +12, Magic Accuracy +10, Magic Evasion +10, Spell Interrupt Resistance +50, VIT +40, Enhancement Magic Potency +10

I find the 'double' benefit of MND to be more attractive (boost to Magic Potency AND Accuracy which helps with landing cures). The Low Cost and vast abundance of MND Materia also makes that a more attractive proposition.

Still a Hard Sell compared to the Chiran Zabran's Tempest which would cost on par with 2x MND IV+20 materia.
