AsciiDoc support in ProseMirror

As a newcomer to ProseMirror, I saw the Markdown example. I was wondering whether it would be feasible/desirable to use ProseMirror as an AsciiDoc editor. Has anybody looked into this? Thoughts?

It should be possible to build this, but it might be quite a bit of work—you’ll need a parser that you can extend, for a start, which for a convoluted language like AsciiDoc might be a serious obstacle.
