is there a straightforward way to extend the org parser to do this?
I don't think so. It seems the emphasis markers are hard-coded in various places. From a quick look at the code, you'd have to customize `org-emphasis-alist` and redefine `org-set-emph-re` and `org-do-emphasis-faces`. Maybe that'd be enough. For the cosmetic part, there's this piece of code from https://archive.casouri.cat/note/2020/better-looking-verbatim-markup-in-org-mode/index.html that displays org's `=` and `~` markers as ```. -- Sébastien Miquel
