I'd be interested in a Sorcerer SCM. They could still arguably pull the Shadow Miracle trick (though that's debatable regardless), an Acorn of Far Travel is just an enchanted acorn, and therefore wouldn't count as a possession, thus allowing use of Earth Spell and Sanctum Spell to utilize Evocation and Conjuration[Creation or Summoning] spells one level before the Wizards.
SCM is generally valuable for increasing a Sorc's versatility (all those potential summons definitely help), and with so many great feat options, there's definitely a lot to gain.
