This is not acceptable. Any solution to the sorcerer problems that involves killing them and giving wixards their toys isn't a solution at all. Besides, it isn't just the spellbook that makes wizards a poor replacement for sorcerers, it is basically EVERYTHING that isn't just casting spells that gets in the way.Alternative fix.
Throw them out. Make a sorcerer subtype for the wizard. Give them the metamagic as their class ability, with the type of metamagic they have access to based on bloodline. Allow them to use charisma instead of intelligence if they wish. Allow them to ignore the need for the book.
