Hmm.  That's a little tricky.  You can of course put your "class_" 
definitions in an arbitrary C++ function, and call that somehow before 
importing the module, but then you really shouldn't call that function 
again when importing because that would register some bits of the class 

I guess I don't really understand how your program flow is supposed to 
work - how did you plan to invoke C++ code from Python before importing 
your Boost.Python module?  Usually the natural place to register 
converters is during module import after you've registered the classes.
