I think so. I have collected a large number of FEN/EPD files from the internet. Some of them are from puzzle books, or PGN/FEN puzzle collections in public domain, some are test suits created by engine developers. So it would be nice to have a way to make a book like Lászlo Polgar's books, with 1000s of positions, with 9 or 12 diagrams per page, and maybe the variations on the back side of each page. I started creating a LaTeX template with xkak, but I don't yet have the script to take a large FEN file and generate an input file for the LaTeX template. I believe it should be easy to write scripts fen2mp and fen2tex. If you would like to see my LaTeX template, I will send you a link by private message. Also, one can directly include a metapost file in a LaTeX file. So what you are creating is definitely quite useful.
