Thanks! Yeah injecting html in the intermediary document doesn't sound very 
promising either (again, because the pages have to be built first before 
footnotes updated with page #s) so maybe I'll abandon weasyprint in this 
case, if this would be easy to do with a *Tex pdf engine. In that case... 
how would one go about this? Would a lua filter be more capable with a 
different pdf engine or would a different mechanism be used?
