You will not be able to accomplish using site sculptor to create the site pages, you will need to create the site pages manually in this case.
probably the best way to accomplish this is going to be to use CSS Menu writer as a plugin page using the PHP Framework.
This way you have one menu that that you add as a plugin to the different templates.
Create each template layout using CSS Sculptor.
Create a blank page and use menu writer to create the site menu.
add the menu page using the framework builder plugin to each sculptor template layout, then save each layout as a template.
