My comment in the bolded section : Wouldn't it be cool if we'd found the barn finds in the same order, but in different places? That would be crazy? :P
Seriously, that idea is great, and doesn't require a ton of effort. The only moment I can see it not be possible is if the cutscenes are based around the barn find, but even then, the commenting, and the assets could be already "tied" to the barn find, meaning that it can be independant from the cutscenes.
