Is there interest in a tool that could take a form-fillable pdf, extract the fields, and then allow someone to just edit a text file that can than be used to create a pdf with the values from that text file in it?
I think I can make it so that as long as your pdf has form fill-able fields you can edit a text file you can edit that can then be used to create a filled-in pdf from that text file.
I'm not sure how clunky it will be as a desktop app, nor if it would be better to be a web app.
Just an idea that wandered into my stupid little brain.
