I think Lankhmar, The Sixth Gun, The Last Parsec, Savage Rifts and Evernight are the only official Pinnacle settings that do not currently have a data file for them. I've got an Evernight file but need to get it fixed up the rest of the way before it can be released, but that being said nobody ever asks me for the interim file anyway so there's not much demand for that (especially so since it's so out of date in comparison to the Fantasy Companion.)
You may have noticed recent threads that suggest Savage Rifts is being worked on but I don't know of anyone working on Lankhmar, The Sixth Gun or The Last Parsec. Honestly you're the first person I've even seen ask for one. I don't have the setting myself so I can't make a file for it and I don't remember hearing of anyone else working on it. It's also not listed in the
Hero Lab Savage Setting Index thread so I'm guessing there isn't anyone really working on it. The closest I found was an old thread where darnet was asking if anyone has started on that or TLP yet, but that's it, not threads about anyone working on it (beyond a post by me saying I don't even own the setting.)
I'm pretty busy right now and will be changing jobs next week, which certainly won't help free up any time, but I suppose if I were working on a setting I'd probably finish off Evernight then start work on TLP next. I might consider helping out with the Savage Rifts after that and then maybe The Sixth Gun, but even for me Lankhmar would be at the bottom of my list (especially so since I don't even own the setting.) Sorry.
Maybe someone else is up for the task or if you want to give it a try many of us here will be happy to help out if you run into any stumbling blocks with it.
