Create a module contains js, css and PHP

[eluser]T-productions[/eluser]
Hi everyone,

I'm developing a CMS with Code Igniter in order to replace my old.
I've developed several modules (clearbox, lightbox, guestbook ...) with this file Tree :

modules
--images
--css
--js
--index.php

All this do a hook included in header. How could I retrieve this concept in Code Igniter ?
I am forced to redo everything?

Any ideas ?
