Using another game engine's api in blender?

I shall keep this simple.
If you knew the api commands for another game engine (ogre, cs, ect.) and you put the librarys in with your game (the .dll’s or whatever) or with blender, could you use the api commands in blender using python?
Like if i wanted to use crystal space’s particles in blender.

OGRE is not a game engine, it’s a real-time renderer.

That said, you can use pretty much anything in blender through python - given that you have a python module for those functions/methods. However, you can’t use things like the other engines’ draw capabilities, because that’s BGEs’ job.

How do i make a python module?
