Well, as an experiment, I've implemented both the q syntax, and http://wakaba.c3.cx/sup/kareha.pl/1102984488/1 on these two boards. Try it out, and give suggestions for improvement or changes.

Yeah, I'm not too fond of the replies link either, but it does make the feature much more accessible. If the reply number wasn't already used for the quoting, I'd use that. Can anyone think up any other more elegant way to do this?
