Hi Leonard, from the master branch, you can now use `org-footnote-inline-footnotes' to convert external footnotes into inline ones.
This is also accessible from the `C-c C-x f' menu that gets displayed when calling `C-c C-x f' from a location where no sensible footnote action can be done, or from `C-u C-c C-x f', which forces the display of this menu. As for converting numbered footnotes into random ones, yes, this should be feasible -- hopefully someone can provide this hack and add it to worg/org-hacks.org. Thanks, -- Bastien
