To my mind, you can do this easily:

import imp, string

st = imp.load_module('st', *imp.find_module('string')) # copy the module

def my_upper(a):
    return "a" + a

def my_lower(a):
    return a + "a"

st.upper = my_upper
st.lower = my_lower


print string.upper("hello") # HELLO
print string.lower("hello") # hello

print st.upper("hello") # ahello
print st.lower("hello") # helloa

And when you call st.upper("hello"), it will result in "hello".

So, you don't really need to mess with globals.
