This is a little ugly, but should work. Make another directory under content that has the name of the url you want, so like content/namereverse/ add a piece of content there (I believe hugo won't make the list directory unless there's content).
Then make a layouts/section/namereverse.html for the reverse section, and just do {{ range .Site.Sections.namereverse.Pages.ByWeight.Reverse }}
I haven't actually tried out that the template is exactly right, but I think it should be pretty close.
