Could we get some screenshots? If I'm reading correctly this is similar to the "Chief Post" for vbulletin? And thanks for posting
edit: In the chief post for vbulletin we had the option of 3-4 different layouts to choose from which is why I asked for a screenshot. I'm assuming the first post on all pages are the same as the standard post in that case no need for a screenshot.
My suggestion is though if this is the case then an option in the admincp of alternative layouts (postbit) that distinguish from the standard postbit look.
