@Eric, see my gist at https://gist.github.com/mklauber/4011a7ea95b158bfcfbf . I've actually got a version of this working, though I'm still fixing bugs, most notably a tiddlywiki script crash if the destination tiddler doesn't exist. Once I've got enough of the bugs resolved with my own usage, I'll open a PR.
