Hopefully, nerfing some of the problem child spells will be enough. Anyway, I'll see if I can put my money where my mouth is and come up with a Generalist Wizard class later today.
And here's what I've got so far:

Class Skills (4+Int per level): Appraise, Bluff, Concentration, Craft, Decipher Script, Diplomacy, Disguise, Heal, Intimidate, Knowledge (any), Profession, Sense Motive, Spellcraft
Proficiencies: As Normal.
Spellcasting: A Wizard gets spells per day, and has higher level spells available to him at the same rate as a normal Wizard, however his spell list is much more restricted, and his spells are drawn from the new Generalist spell list. In order to cast a spell he must have an Intelligence score at least 10+spell level, and his bonus spell slots are determined by his Intelligence. The saving throw DCs of spells he casts are determined by Charisma. Wizards know all cantrips from all spell lists and can cast them at will.
A Wizard begins play knowing 3 1st level spells, and learns an additional spell of any spell level available for him to cast at every class level. Wizards may record additional spells into spellbooks. If a Wizard chooses he may learn an additional spell at each level but these spells must be transcribed into a spellbook. If he does not have access to the spellbook he may not prepare spells learned in this way.
Bonus Feats: At first level a Wizard gains Scribe Scroll as a bonus feat. He also gains bonus feats at 5th, 10th, 15th, and 19th levels. These feats can be any metamagic, heritage (counts as a Sorcerer to qualify), item creation, or reserve feats that the Wizard qualifies for.
Spellgrace: A Wizard adds his Wisdom modifier to AC against spells, spell-like abilities, and supernatural abilities. He also adds the bonus indicated by the table to his saving throws against those abilities.
Sense Magic: As Swordsage.
Advanced Learning: At the indicated levels a Wizard can add any spell from any spell list to his list of spells known so long as his Wisdom score is at least 10+spell level. A spell added this way must be at least one level lower than the highest level spell a Wizard could normally learn.
Something Awesome: It is what it is. At 20th level, a Wizard gets something awesome.
