Confederations Cup 2013 Brasil...?

I understand we have a qualifier in may and then their is I think a one and a half week gap before we play our first match in the Confederations cup against Italy in Rio. I was thinking whats the chance or would it be wise for the Mexican national team to set up a brush up game against a local Argentina national team side in Argentina because I know it won't be a Fifa date. I know Brasil and Argentina played a with local a local national team not that long ago, but what do you people think on here about a brush up match?
