Maybe it'd be overkill, but it's possible to teach Python that urllib3 
and requests.packages.urllib3 are the same thing. Adding something like 
this to the top of requests/__init__.py should do the trick:

import pkgutil
import sys
import urllib3

def _attach_namespace(package, where):
   for loader, name, ispkg in pkgutil.walk_packages(package.__path__, package.__name__ + '.'):
       try:
           module = __import__(name)
       except ImportError:
           continue # oh well
       sys.modules[where + '.' + name] = module

_attach_namespace(urllib3, 'requests.packages')
del _attach_namespace
