So... I had a few ideas for a series of homebrew feats for spellcasters... I call them Academic feats... the idea behind them is essentially an alternative to Theurge/Gestalt/Ultimate Magus... etc... So let us begin...
Academic Research
[Academic]
You just can't put down your spellbook even after preparing your daily spells.
Prerequisite: INT 13, Must Prepare spells from a spellbook (or similar), caster level 3rd, Scribe Scroll
Benefit: As a full round action you may search through your spellbook for a known spell that is not currently prepared, up to 1 level lower than your current highest known spell level, and prepare it to cast at the start of your next turn. This action always provokes an attack of opportunity, you must make a concentration check DC 11+Damage Dealt+Level of the spell you are preparing or lose your place and have to start over.
Special: You may take no further actions until after you have cast the spell. This feat does not qualify you as a spontaneous spellcaster. This feat may not be taken along with Academic Study.
Note: You do not gain any additional spells per day from this feat. This feat cannot be applied to 9th level spells, even with epic spells.
Academic Study
[Academic]
You're dedication to the academic arts has granted you a brief understanding of spellbooks.

Each day you may prepare 2 spells of each level, up to 1 level lower than your current highest known spell level, from your spellbook. You may add spells to your spellbook in the same manner as a wizard, however all spells must be found on the qualifying class's spell list.
