Is it possible to replace the default header and footer with a module like other reports where you can call them in .xml with <report> label?

For example to replace the sale order report,

<report 
            auto="False" 
            id="sale.report_sale_order" 
            model="sale.order" 
            name="sale.order.myreport"
            string="Sale Order Report"
            usage="default"/>

Wich is the id and model in that case? Thank you

PS: I don't want to use another report engine (aeroo, webkit, etc). I want to replace the rml if it's possible to do.
