It's probably safe, but I don't really see the point in it. Between F95 and ULMF+qbittorrent you have all the content you could ask for. If you want Law Lee content, just browse DLsite for a bit, find a game you like, paste the RE/RJ code into qbittorent's search feature, download the raw JP files, look up Yugifan3, apply one of his many partials and voila, you have a playable game on your hands. I can go into more detail if you get stuck along the way. But yeah, this method will open up a whole new world of smut gaming you can't find on F95.
