Hi Jason,
Sorry but there is currently not a way to make the blog detail pages use a different skin than the one used by the page containing the blog.
What you might try is create a bog on a different page than the home page (don't try to move the existing blog to another page, just create a new one). Then on your home page use a Feed Manager module to consume the feed of the blog. So the feed manager would be your "News" module. Then you can apply whatever skin you like on the page containing the blog. Links from feed manager will go to the blog posts.
Hope it helps,
Joe
