This is impossible as long as the Google SDK isn't Python 3 compatible. To get around the problems with them depending on the C versions of modules you can put something like this above the imports:

# python 3 fix for Google relying on C versions of modules
try:
    import cPickle
    import cStringIO
except ImportError:
    import _pickle
    from io import StringIO
    sys.modules['cPickle'] = _pickle
    sys.modules['cStringIO'] = StringIO

Which gets you somewhere, but eventually the code hits something like this and we can't start live-patching their code to get around all these cases:

raise ProtocolBufferDecodeError, '\n\t'.join(dbg)
                                   ^
SyntaxError: invalid syntax
