For new feats, how about healing touch:

Your healing hand becomes more like the healing touch of angels. A creature affected by your healing touch is freed from any curse, disease, poison, blindness, or deafness.

You could also make a variant of elemental adept that lets you ignore resistance to radiant or necrotic damage for spells and radiant soul, radiant consumption, or necrotic shroud.
