Sadly that's not doable for us. LaTeX, for all its benefits, has terrible user experience and would drive away a lot of authors. One of the benefits of using PDFs is that anyone can use almost any tool they feel comfortable with to make the article (except for Photoshop - we banned Photoshop PDFs because they are ridiculously constructed). For example, I use Google Slides for my articles (which seems like a weird choice, but it's so easy to do complex one-of formatting in it).
