If it'd drop Conjuration, I'd rather not. Also, 3.5 wizard over PF wizard, as is the guideline.
Make him a Focused Specialist of Abjuration or Transmutation, which I feel fits him, and dro Necromancy, Enchantment, and one of Evocation or Illusion.
He can enter a PrC at 3rd or 4th level, too: Master Specialist. Pretty good.
And it fits that his super early, unguided study would allow him a path to power that, while being very powerful (we are talking as many spell slots as a sorcerer here), is not without its flaws.
