Well, you can just inherit with a class from zopes extension classes.
You cannot modify the class bases like this with extension classes.

You can work around that like I did with the history (monkey) patch:

Otherwise it sounds evil and you failed to show the true
motivation with your example above.

PS: Votes for a true implementation in current zope instead
    of the monkey patch? If so, tell me.
