What if, instead of metamagic being a feat, it was always done in the fly as part of a Spellcraft check, DC determined by the LA of the former feat?
Then, instead of there being a host of metamagic feats, there was only one- giving a bonus to the check? (Given other feats that boost skills, you could only take this one once...possibly with a prereq.)
