I haven’t seen any fully baked wordpress like solutions out there but checkout our site: https://github.com/serverless/site it’s built with phenomic.io and hosted on a CDN via netlify.
We are using auth0 for user login/auth stuff and have a couple of serverless functions handling various web tasks.
One thing that I’m looking into is an admin like interface for the static site by using: https://github.com/netlify/netlify-cms
