exporting imports to reduce exe size?

[Ron_Adam]

In looking at ways to reduce the size of exe's created with py2exe,
I've noticed that it will include a whole library or module even if I
only need one function or value from it.  

What I would like to do is to import individual functions and then
export 'write' them to a common resource file and import that with
just the resources I need in them.

Has anyone tried this?  

I'm considering using pickle to do it, but was wondering if this is
even a viable idea?  

Is it possible to pickle the name space after the imports and then
reload the name space in place of the imports later?

Cheers, 
Ron
