I don't use anything more complex than a drill or dremel when hand fitting my own personal projects, so sitting with a set of micrometers and a few good files is how I would personally take on this mount. The problem is that you're looking at a lot of work for a low amount of return, if any. There are so few of these lenses available because they were just too expensive when originally sold, they were low volume sellers. For the few out there that haven't been "converted" to M mount, there isn't much of a larket for this particular adapter. If you do 3 pieces, you're looking at a specialized mount at no less than a few hundred US dollars per adapter, along the lines of what Amedeo has done with the Contax/Nikon adapter line. He'd actually be the guy to talk to but there is a much bigger market with a wide variety of glass to stick on an LTM or M mount than there is interest in the 50/.95, solely due to lens availability and price. You might be able to find a TV mount version of the lens that hasn't been butchered to make an adapter off that as well. Either way, with only about 27,000 samples of this lens ever being produced, it's pretty rare. It's not 2.1cm f/4 Nikkor in Nikon S mount rare, but it's certainly uncommon enough that one has to be nearly obsessed to find one. One way might be to find a trashed Canon 7 and scavenge the flange from it, you're going to need it out of the camera regardless, to get precise measurements.
As for an LTM to Pentax K mount adapter, that's easy, you might be able to find an M39x1 adapter for Zenit to original Contax. You could always just find the Zenit camera and rip the flange off then add the K adapter. The only problem you would have is it won't focus to infinity without a negative element. You'd be pushing the infinity focus of the LTM lens to maybe an inch or two since the Zenit registration is 45.2mm. It could easily be fudged for Pentax since the registration is 45.46mm.
Have fun and post photos if you get to it.
