First of all, there is no special "text layer" in a PDF, the page content is (at least may be) a series of operators either adding text glyphs or graphic elements to the page at some coordinates or changing the coordinate system or clip area for the operators to come. In general, therefore, changing the content means quite a challenge, especially if those changes are also expected to move text following on the same line, maybe even pushing a word into the next line, maybe even thereby inserting a new line, for the simple reason that there isn't a concept of text lines, text paragraphs, headers and footers, etc. in PDF (at least no such concept you have to respect or implement when creating a PDF). Thus, unless you have source PDFs which are very tidy and contain certain optional information, I wouldn't even start to try to automize that process.
