Backreference within a character class

For the Python RE gurus:
Using the re module, lets say that I want to match "XIX" but not "XXX"
or "WOW" but not "WWW". In my first attempt I used r"(.)([^\1])\1".
This, of course, did't work because the "\1" in character class isn't
interpreted as a backreference.
So is it possible to specify a regular expression to match these
patterns?
Thanks,
