Using PDF's as templates

In seeking to edit/modify I found out that is pretty much impossble, but for what I was wanting to do that was probably sub-optimal

However it occurs to me that it might/could be possible to use a PDF document as a template.

So: Is this possible and is it a good idea?

Sorry Mariosv, not what I’m after, I want to turn the PDF into a Writer template
