HiTorkj,
Unfortunately there is no way to regularize your situation without leaving Brazil. Even to apply for a different kind of visa, which would get you around the 180 day per year rule you'd still need to apply from outside Brazil.
I know that's not the news you want to hear, but it's the only news I have to give you.
Cheers,
