At times, I've merged books in a series and ended up with files larger than 50MB but as long as the html files are reasonable sized, I've haven't seen any issues. I also have multiple books that are in the 200-390MB range for a single book but these are cooking related books that are heavy in images.
Thanks for the feedback. I'm using the calibre EPubMerge plugin to do the file combinations, and that seems to handle this correctly, the individual book files are kept separate in the merged book, so there shouldn't be any single huge internal ePub files.
