Possibly; at least in some form it does:
- https://github.com/chasberry/orgmode-accessories/blob/master/ox-ravel.org

Yes!

> • Has anyone else ever thought of doing this? If yes, why didn't you?

Yes:
- Don't know elisp
- Found the above, which mostly worked. I had to edit my Org file to
feature a carriage return between text and my lists. ox-ravel appears
to export literally, and it appears knittr won't pick up a list if
there's no blank line between regular text and a list. In other words,
this:

list
- item1
- item2

Isn't the same as this:

list

- item1
- item2

Probably a simple enough fix, but just pointing out one nuance that
org in general and other exporters don't struggle with (they recognize
a list even with no blank line).

See if the attached are satisfactory
- test.org: just a heading, a couple lists, R code (and output), and an image
- test.Rmd: output of ox-ravel Rmd exporter
- test.html (well, a screenshot): results of opening test.Rmd in
RStudio and knitting


Let me know what you think!

Unordered list

- How does this work?
- Simple list
- 'Nother item


Numbered list

1) Switch it up
2) Numbers this time

Some code:

#+begin_src R

x <- 1:10
y <- x^2
