Is this possible with several category views ?

Hi again,
I have a question about categories and view.
As it is possible to call a module anywhere in a page, is this possible to call 2 or 3 (or more) category listing in an article ?
I know that i can use a universal module, but my category list use specific template for listing : if i use a module, i will lose my category template.
The goal is to get something like :
- Name of the cat 1
-> Listing of the category present as done with my category_item.php
- Name of the cat 2
-> Listing of the category present as done with my category_item.php
- Name of the cat 3
-> Listing of the category present as done with my category_item.php

Is this possible or not ?
Thanks
Xavier
