It's been a while, and this is from the top of my head, so it may not
be completely right :)

While it would be a significant piece of work, I don't know whether it
would be more than the rest, IIRC there would be two big things that
need to be done:

1. I think a few object formats have been added for PyArg_ParseTuple()

If so, some of them may not be trivial to port back (there is a reason
they got added :)), but the simpler ones haven't changed I think. This
is also the place you'll run into the unicode differences between 2
and 3 (but that may actually make the code for 2 simpler).

2. Update initialization code for each wrapper

this should me more repetitive than hard.

And of course there are probably other incompatibilities I don't know
from the top of my  head :)

In general, with some exceptions, yes I think it is a lot of work, but
mostly repeating the same process, so in that sense the diff would be
larger than the effort, so to say.
