I was wondering the same thing. I stumbled upon Keystone this weekend and it's the one that looks the most promising. Only cons is mongodb, it's lacking per template custom fields, and is not very designer-friendly. I have in mind a straightforward CMS in Node/Express and Postgres, that would combine some ideas of Wordpress's Page/Posts and Taxonomies, and the Advanced Custom Fields plugin. The whole schema would be defined by the theme, and each template could provide its own custom fields, with no admin-side configuration. And the CSS classes would be scoped to the template in order to avoid conflicts. I'm no strong developer, so would probably need collaborators to help me out.
