The market has been needing a tool like that for 30 years. A PDF document of the type I describe is like a broken egg. Information is lost between the authoring and rendering, to the extent that it's not clear recreating the original is even possible.

A typesetter could recreate the document through looking at it, doing some font research, and playing with the kerning for a while. Saying it's not possible to recreate a typeset document that is readable is absurd, no matter how twisted and insane the actual postscript is.
