That depends on what you mean by Zope 3.  If you define "Zope 3" as   
zope.app.server.main, or zope.app.twisted.main, then yes, it is. I  
wouldn't define it that way, although I can see how others might. :)

You would need to write a different main program that did something  
else. You would need to understand how the publisher framework worked  
and plug in an alternate publication that traversed to non-ZODB  
objects. Unfortunately, these frameworks were written before we got  
the doctest religion, so there's no document that I'm aware of that  
explains how to do this. It isn't very complicated. I have a strong  
itch to write such a document, but I don't know when I'll get around  
to scratching it.  I don't know if any of books get into this.

Other people have already made this happen. I don't know if any of  
their code is public or if they have written up what they've done.
