In this particular case, you should explain why you want to replace filesrc, and add the features you need to filesrc - or (more likely) we can suggest a better way to accomplish your goals. To more directly answer your question, playbin2 (you should be using this instead of playbin) will select the highest-ranked element that can handle the uri it's given, so you'd give your new element a higher rank than filesrc.
