Why do you care so much about the file name? You can anyway use only one at time.
The file has to be named ddraw.dll, for system to load it up automatically. DirectDraw api will load it up by default, if you change the name it won't start up and you would have to find a different way (most likely modding exe file) to pin it to the game.
