What next?

Have you thought of Jekyll and/or Scriptogram support? I'd be glad to assist if I can, may need some pointers (but I grasp concepts quickly. As long as they're not about LESS or Sass) ;p

I have. There is a fair amount of Wordpress specific stuff (both in terms of code and design), but it could be an interesting refactor to try and support another platform. I haven't looked into any other APIs though, so I'm not sure how similar they are.

Jekyll-wise: I helped out with some minor doc work on the jekyll-import gem, as it says on there - if you look at Migrations (to Jekyll),

(just two pointers as to how closely Jekyll has been tested to integrate/acccomodate WP's formatting and/or API. In the second img you can see there's even a migrator to wire into the MySQL db itself.

Scriptogram, it's even simpler than Jekyll as it lives in a user's Dropbox, but uses YAML front matter and partials like Jekyll does, but in slightly diffferent ways. Jekyll uses Liquid, I'm not too sure about Scriptogram. Jade perhaps. I run a Scriptogram blog - it's so lightweight, yet powerful, that it's almost ridiculous.

I don't know if that helps with your perception as to how much work would be involved
P.s you may have already, but in case not, look at Stackedit
