Just to make sure I understand what you're after, you mean something like this?
I had to take a theme (Carbonize) and customize it (re-write the page layout) so that it didn't display the blog's sidebar. Now, every static page on my WP install shows as full width, but the Blog (only) shows the side bar menu with previous blog entries, etc.
It was some work but since I'm HTML and CSS savvy, I got it working in a day or so. You might want to find or pay someone to develop a theme that is built that way from the start.
