How would you address Button Bloat on healers?

Edit: Maybe having it only affect heals for healers is the way to go; Have damage remain as-is since there is a significantly lower number of damage abilities. Or, have a separate stance for Damage abilities and Healing abilities for healers.

I saw a WHM suggestion a few weeks ago to make WHMs work like the final boss of Amdapor (the stone angel) where they could have some Eucrasia-like ability that converts their heals into damage like that boss does where she converts her "Cure X" into a damage spell. So using this ability than Cure 3 would make it into Holy, for example.
