Definetly it's a huge work.

NumPy is already big. I'd start with a very small project like the
sample at http://docs.python.org/ext/simpleExample.html. Sort of a
proof of concept.
Have you evaluated that you may need to port a big portion of the Python
C API (Py* functions and macros.)?

As someone else already said, you ought to consider COM too.
Another aproach is to completly forget the *CPython* extension. Pick
the domain C code core and add a .NET wrapper. Swig can you help here:
In these two approaches a Python compatibility layer API will be needed.
Thus, the programmer can use the same API from IronPython that she
used to use from CPython.

Hummm... I'm tempted to add a silly joke here but I'm going to refrain
myself now. ;)
