What's wrong with it?  I would probably adopt a similar approach.
My own thoughts have been to use "jay" for the Python grammar
and obtain a parse tree of the Python code to be compiled.
(All in C# btw). Walk the parse tree and use System.Reflection.Emit
to create the byte code.

I think that the real problems are to do with mapping the
semantics of Python to .NET; this I can't yet comment
on, I haven't researched it enough.  I was wondering about
doing my research by hacking MonoPython and seeing exactly
why it won't work :-)
