Can I merge a series of editable PDFs made in LibreOffice

Background to question

I need to split a document. While I read an answer that suggested using the Master document, it occurred to me this way might be easier; however, I would like to know if this is the case.

Question

If I create a series of PDF documents from the original. Say, chapter 1, 2 and so on, can I then recreate the full-length document by inserting all the PDF’s into a large file? (Obviously, embedding the file so they can easily be edited in LibreOffice Writer.)

Are there any pitfalls?
