New page template- strange page layout request

I want/need to create a new page template that combines layouts of different page templates. The template flow would go:

full width (content)
sidebar (standard main content width); sidebar (standard sidebar size)

I'm not sure how to set up the template to allow this kind of layout. The need for this is predicated on the idea that only one nivo slider plugin seems to work (FIAGallery) without breaking basic WP/BP functionality, and uses images from the media gallery, but it can only be deployed to a page using short code, and I need the banner to extend the width of the page. The rest of the content for the page I'd prefer to be standard content, but will live with it if I need to work with an oversized text box (hoping that will work).

Thoughts? Feedback? Guidance?
