There is no supported NT4 PDC demotion scenario. But via registry hack
I think you can demote to server and then become a member server. And
Exchange 5.5 can run on member server.

That's one reason for dealing with the VM's. I'll be able to test
these changes in a separate virtual environment. Just would be nice to
know if anyone has actually done this and, if doable, what the caveats
and gotchas were.
