And I was able to roll my own embedded image conversion with some tweaking. I had to change embedded format above from "data:..., " to "data|" (substituting the colon and dropping the encodings), and then hooking PreRenderDocument and iterating through all images like the abbreviated error-checking-absent code below.
If there is an easier, more supported method, or more standardized method, please do let me know! And if you accept the "data:" feature, I am still interested - better a portable format.
Hope this helps the rest of y'all! Cheers.
