While the concept of antimetamagic is quite cool and original, as stands I can't see it without a serious abuse problem. With enlarge alone, you can drop the spell levels of some key spells. And often the range isn't all that important. What about antiheighten? That could be really nasty.
Of course I think the antimaximise would be funny. I throw a fireball, and always do 10 point of damage as a 0th level spell
