Is PDF generation via LaTeX not practical to achieve?
Your PDFs are pretty good, but the basic aesthetics could be improved another small step via LaTeX generation... the main trick you'd probably want, in order to avoid overfull lines (at the expense of many usually not nearly as egregious underfull ones), is to set \tolerance to 9999. That way, while less than perfect, the LaTeX output is all but sure to not be blatantly erroneous on account of text being cut-off.
