Here's how I was thinking...
Let's say we start with a magic missile. Apply to it the Maximize feat, bumping it to a 4th level spell.
Now you have a max magic missile as a 4th level page for 16000gp using 4th level spell slots. It's already augmented with a metemagic ability essentially "prepared" as such, so as a sorcerer you aren't applying the feat on the fly.
On the down side, the spell no longer "floats", it is fixed at its metemagic level. If you don't have the spell otherwise, it ONLY exists as a 4th level spell. Also, the metemagic is only applicable to this spell.
