Here's a status report:
I've started a Z2 publication object in the 'publication-refactor'
branch of Zope 2.
Awesome!
I am not 100% sure this is what you had in mind, but basically i've
broke down the 'publish' method from ZPublisher.Publish into the
methods of IPublication, and it seems to have mapped quite well with
some minor exceptions.
Cool. It should. IPublication was designed by insoecting all
the odd hooks in Zope 2.
I haven't gotten around to implementing the traverseName method, which
will need some deep surgery on ZPublisher.BaseRequest.
Now, what I have in mind moving forward is to replace the code in
ZPublisher.Publish and ZPublisher.BaseRequest to use the Zope 2
IPublication instead of duplicating code once I'm done with
implementing the interface.
My only fear so far is that there might be some issues with the
request object itself being not 100% backwards compatible, but I think
we can have backwards compatibility implemented as an adapter from the
Zope 3 request to Zope 2 request.
Possibly. Note that the request itself is pluggable. Zope 3 has a
notion of request factories. When you set up a particular server,
you can specify which request factory is used. It would be nice though
of Zope 2 and Zope 3 requests could be handled by the same server
(host/port).
Adaptation may be a good way to start, although arranging for the
adaptation to happen could get interesting.
It might be better to see if we can come up with a request that provides
both Z2 and Z3 request APIs, if possible and then start a process of
deprecation of features we don't want in the future. This might
be easier and simpler than adaptation.
How does that sound?
Sounds like a great start.

Great.
