Have you considered antora jointly with asciidoxy ?

Antora is a documentation site generator using asciidoc and asciidoctor. Have you considered using asciidoxy to generated a component for Antora ? Some discussions here https://antora.zulipchat.com/#narrow/stream/282400-users/topic/thoughts.20on.20antora.20for.20automated.20reference.20documentation.20.2E.2E.2E (antora zulip chat) after I discovered asciidoxy. It seems that asciidoxy would be a nice candidate to generate automatically documentation from doxygen and publish it with antora
