Load all favorites to the page and save it, export as JSON data or just copy the textbox contents. Works on exhentai and e-hentai.

No, you cant get the archive links with the information from the favorites page.
But if you save the regular gallery links, there are some other ways to download the archives of those links.
I never used anything like that so I can't give you a link; but I can confirm that it exists.
Archive link as well?
Is it possible to scrape the archive download link as well together with the torrent link?
