I am all for this; rebalancing where possible is always nice.
... Though, I am curious to know whether the Harper Scout's "Spells" are supposed to be actual Spells, or Spell-like Abilities; the main reason for doing this would be buffing Harper Scout so it can do stuff like qualify for PrCs that need spellcasting to begin with. If they're just supposed to be Spell-likes, then it would be better to just leave 'em alone. >_>
