Could we get some screenshots? If I'm reading correctly this is similar to the "Chief Post" for vbulletin? And thanks for posting
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.
