Does anybody know how I can convert my FAA or my ICAO (Argentina) license into JAA ?

I don't think you'll be able to avoid the written exams and all the rest, my friend ! Check the JAA website: http://www.jaa.nl

But the first question you should ask yourself is: "Do I have the right to work in Europe ?". Up here like anywhere else on this planet, you'll need a working permit or a European citizenship.
