That's super interesting, I am in the same boat. Do you mind me asking what graphics format(s) you're using? We're using a sort of hybrid Asciidoc/S1000D approach, Asciidoc markup with S1000D architecture (filenamers, publication modules, data module codes, etc). The art is SVG brought over from CGM, with conditional content (applicability) controlling the images via a new module type we call "illustration control files" that toggle the art based on "applicability" aka asciidoc document attributes and ifdef/ifevals. PDF is via DocBook-XSL, but it's a scheduled process and not "on-click", which I am positive would break things. I am not even sure how to fire fopub from this company's web architecture; they wouldn't let us post html to a network directory (argh?), so any hopes of doing something more advanced are pretty low. In my off time I am looking at Antora pretty hard, and web-pdf is going to be the default pdf tool for that build platform. One thing I am wondering is how Antora's playbook files are going to relate to the "Ascii1000D" Publication Modules, which overlap a wee bit.
