On one hand I like this, and have used similar visuals in presentations, on the other hand I feel it's a less a problem related to math literacy per se, and more needing a workaround relating to the artificial limits and style restrictions imposed by journals (as well as the limitations of a paper medium, to some extent). The whole "pay £1000 per extra page" by itself has been enough to reluctantly cause me to cram math inline and assume symbols are known to the field without too much explanation.
