I had an idea and think it should be interesting to share (with a little pushing, you know who you are! ), so here it is!

Soothing Touch
Prerequisites: Access to Healing or Suffering domain or remove disease spell-like ability, ability to channel positive energy or variant paladin of Cuiraécen.

Benefit: You may convert any spell you have prepared for any of the following spells, as long as the prepared spell you convert is at least 1 level higher than the spell you want to cast and that the latter appear on your spell list:
atonement, break enchantment, calm emotions, delay poison, freedom of movement, heal, neutralise poison, regeneration, remove blindness/deafness, remove curse, remove disease, remove fear, remove paralysis, restoration (lesser, [normal], greater).

If you have remove disease as a spell-like ability, you may spend one use to cast remove blindness/deafness, remove curse, or neutralise poison, using your caster level. You can supress all ill effects, including blindness, confusion, daze, deafeness, exhausted, fascinated, fatigue, fear and its effects, nausea, insanity, paralysis, poisons and their effects, sickness, and stunning, but nothing else, for 1 minute per level times your Charisma bonus (minimum 1) by spending one use of remove disease. These count as uses of the remove disease spell-like ability in all senses.
