PA44,
It's possible to convert your license, however medical, theory and flighttesting is required. That said, you have very slim, if not no chance of getting a job in Brazil currently especially in the current airline-situation Brazil is in. I recently tried it myself. If you have no brazilian passport, your chances are already pretty much down to zero. And seeing you have very little hours, i would advise you not to even try. As mentioned before, if you know some good people there, you might give it a shot. But i would focus on something else.
