A couple of thoughts:
If you want to get rid of magical healing, let the PCs heal 1 hp per level per hour.
Goodberry is a subtle (but weak) healing spell.
If you want to balance the classes while changing the magic system, you might want to get rid of the spellcasting classes (wizard, sorcerer, cleric, and, to a lesser degree, druid), replacing spellcasting with a skill and feat system available to all characters.
