Actually, if you can get Metaphysical Spellshaper allowed, you can get cantrip miracles from the original slot. Between the -1 there, the -1 from Incantatrix, the two slot bonus from Earth Spell, the -1 from Arcane Thesis, and the -2 from Halruuan Elder, all you need are like two more reductions. Practical Metamagic, Easy Metamagic, and one other gets you to 10th level spells from a 0th level slot, which can be done via Sanctum Spell. Congrats, you're now casting cantrip shadow miracles! Also, check my thread in the You Break It forum about stealing the erudite's thunder...it shows how to abuse the action economy with psionics using a wizard base.
