There are only a few modules that you really need to do this for for 
beginners.  Trying to convert the entire stdlib, let alone other stuff 
on pypi, strikes me as foolish.

If possible, and I presume it is, make your interpreter dual language. 
Source code in .py files is parsed as now (and module compiles to .pyc). 
  Source in .pyb (python-brazil) is parsed with with your new parser, 
and get a brazilian equivalent of builtins, but use the same AST and 
bytecode.  Bytecode is neither English nor Brazilian ;-).  This would 
give your students access to the whole world of Python modules and allow 
  those who want to move to normal English-based international Python to 
do so without obsoleting their existing work.

PS. Since this thread is not about developing Python itself, it would be 
more appropriate on the python-ideas list if continued much further.

PPS Once unicode identifiers were allowed, I considered it inevitable 
that people would also want native-language keywords, especially for 
younger students.  So I expected a project like yours, though I expected 
the first to be in Asia.  I think dual language versions, if possible, 
would be the way to do this without ghettoizing the national versions. 
But as I said, a general discussion of this belongs on python-ideas.
