Give in to the Dark Side, you know you want to.
These feats remind me of a feat I had in my files for quite some time now:
[sblock]Expanded Studies [General]
Prerequisites: Specialization in a school of magic, Knowledge (arcana) 6 ranks, Spellcraft 6 ranks
Benefit: Choose any school of magic, except your specialist or forbidden schools. You get a +2 bonus to Spellcraft checks when dealing with a spell or effect from your chosen school. In addition, you may prepare spells of the chosen school in your specialist bonus spell slots.
Special: You can gain Expanded Studies up to two times. Each time you take the feat, it applies to a new school of magic.

Daryne's Imagination
Prerequisite:
Academy Graduate, Illusionist or Evoker, not barred from Illusion or Evocation, Int 15+
Benefits:
You may now select your specialist bonus spells from either Illusion or Evocation spells. You do not receive any additional bonus spells, however. Additionally, those who wish to expose your Illusions with Divination spells must succeed at a Caster Level Check DC 5 + your caster level or the spell is fooled into believing the illusion is real.
I'm not quite sure how this should work. Can you give some examples?

Benefits:
You may now select your specialist bonus spells from either Divination or Abjuration spells. You do not receive any additional bonus spells, however. Additionally, you may make any Knowledge check untrained.
Seems reasonable. Remember that specialists can't be barred from divination.

Academy Graduate, Enchanter or Conjurer, not barred from Enchantment or Conjuration, Int 15+
Benefits:
You may now select your specialist bonus spells from either Enchantment or Conjuration spells. You do not receive any additional bonus spells, however. Additionally, you have become efficient at crafting new magic items in your spare time. You spend only 75% of normal craft points when using Item Creation feats. You still pay the full gold and XP costs.
Good.

Sice's Power
Academy Graduate, Transmuter or Necromancer, not barred from Transmutation or Necromancy, Int 15+
Benefits:
You may now select your specialist bonus spells from either Transmutation or Necromancy spells. You do not receive any additional bonus spells, however. You gain Intimidate as a class skill. Additionally, after casting an offensive Transmutation or Necromancy spell with a visible damaging effect on your enemies, you may make an Intimidate check against all targets of the spell as a Move Action. If you do so, add the spell's level to the Intimidate check.
Might work better as "all affected creatures" rather than "all targets." Area spells, for example, have no targets.

Would spells such as Waves of Fatigue count as damaging?
