That's only works if your DM doesn't read the Complete Mage Reserve Feat Header closely.Have you considered Alacritous Cogitation + Heighten Spell + Reserve Feats?
Since you can (potentially) cast any spell you know using the slot, you can empower all Reserve Feats you have with it.
The Heighten Spell is, of course, to lift your spells to the level you have the open spell slot.
See, it seperates out the requirements - "A spellcaster who prepares spells each day (such as a wizard) must have an appropriate spell prepared and not yet cast" (Complete Mage, page 37). For "A spellcaster who does not need to prepare spells (such as a sorcerer) must know an appropriate spell and must have at least one unused spell slot of that spell's level or higher"
Now, while this may technically let Alacritous Cogitation work (you don't strictly need to prepare spells, as you can cast spontaneously... once per day...), Heighten Spell doesn't work with it - when you have heighten spell, you don't technically know that spell at that level, you have a means by which to cast that spell at that level.
