So I had slight idea of "what if WHM healed in the same way that BLM does damage?" where you swap between Healer Stance and Cleric Stance. Using a healing spell puts you in Healer Stance and nourishes the Blood Lily or gives procs, while using Banish III puts you back in Cleric Stance to let you regain MP and spend those lilies and procs.
The stances have no timers involved, this should make it less stressful to play compared to BLM, but gives a similar gameplay style that focuses more on a healing/damaging dichotomy.
Stances:
Cleric Stance: This stance lets you build Justification stacks and use Glare and Misery. Also increases MP regen by 300%. You enter this stance by casting Banish under no stance, or Banish III while in Healer Stance
Healer Stance: This stance lets you nourish the Blood Lily and the Epiousian proc as you heal, and reduces the cast time of damage spells by 75%. You can enter this stance by using any healing spell.

Xenoglossy but with a refund attached.
Glare
Spell -- 1 Justification -- 3s Cast time
Deals unaspected damage with a potency of 300
Can only be used under the effect of Cleric Stance
I can't believe it's not Fire IV
Banish III
Spell -- 0 MP -- 3.5s Cast time
Deals unaspected damage to target and all enemies nearby it with a potency of 260 for the first enemy, and 30% less for all remaining enemies.
Grants 3 stacks of Justification while under the effect of Cleric Stance (does not grant stacks when swapping from Healer to Cleric)
Grants Cleric Stance and removes Healer Stance
I can't believe it's not Fire III, cast time is reduced by 75% while in Healer Stance as well.
Afflatus Misery
Spell -- 1 Blood Lily -- 0s Cast time -- 60s Recast time
Deals unaspected damage to target and all enemies nearby it with a potency of 540 for the first enemy and 50% less for all remaining enemies.
Potency increases up to 1140 as Blood Lily exceeds minimum cost
Grants 3 stacks of Justification
40% chance next Banish III will have no cast time
Can only be used under the effect of Cleric Stance
Still a refund, but also acts as something like a Paradox equivalent.
