Short answer: no. Longer answer:

The Dia python *plug-in* embedds Python, it only allows to write Dia plug-ins.

Depending on your use case this might be possible still be possible by 
os.popen ("dia --..."), aka. as command line driven.

They all have either a call to dia.register_action() passing in a menu path 
where to register or

dia.register_export() or dia.register_import() to register the for fileio.

This is not any longer PyDia specific. Very few Python modules already do 
much (beside registering/initializing) during import. You usually need to 
call some function from the module.

Some very minimal examples for "reusing" Dia python plug-ins are the test 
script in the second bindings
