Any more info on how the HP world was 40k-ized?

Very cool. I will use this somehow, some day! :)

Let's go for some obvious ones- Dune. Can be run pretty much straight out of the box, albeit you may need to turn the stakes down slightly (Shaddam IV Corrino can hardly be the Emperor, for example). But desert planet that produces a rare substance that can enhance psychic/navigator powers? Dynastic squabbles and intrigue? Wars fought over trade monopolies? Sounds about right.

Forbidden Planet (or, of course, the Tempest, the Shakespeare play it's based on). The Explorers stumble upon a destroyed world, inhabited only by a small archeoxenan research camp run by an eccentric/insane academic, his daughter and a cyborged bodyguard/servitor. The Academic is playing around with a psychic enhancer left from when the Enslavers ruled this part of the galaxy (change precursor race to fit, but the Enslavers is particularly apt, as they are sometimes known as the krell, who were the ancient aliens from the actual movie). The Explorer's shuttles are seriously damaged/destroyed by an "invisible beast", which, unknown to pretty much all, is a manifestation of the Academic's latent psychic abilities, unleashed by the technology the Krell left behind. Shake and serve, with the fun twist that the Krell devices could well turn even non-psykers into hosts for an Enslaver infestation…
Definitely worth grabbing Creatures Anathema for that one.

Rocky Horror (Picture) Show. Bear with me on this- The Explorer's ship suffers some terrible tech failure, leaving them effectively stranded in system, but as luck would have it, there's an active dock in the system, which looks to be fairly crowded with the sort of craft that might be owned by the idle rich (or other rogue traders). Indeed, there seems to be a festival of some sort taking place, and the Explorers are invited to join in the celebrations while their ship is being repaired. The host and guests seem rather sybaritic and hedonistic, even to the jaded star-travellers that make up a typical Rogue Tradder dynasty, and it gradually becomes clear that they have sorcerous powers. Then comes their Host, the Baron Frank-N-Furter's triumph- a patchwork amalgam of parts to create his own "astartes" slave*! Throw in some slaaneshi sorcery, mind control, and so on, and there you go.

*May work better as a patchwork daemonhost. Must think about that.

Bonus points, of course, for working in quotes from the original sources and seeing if the players notice…

The Call of Cthulhu. Alien and/or Chaos cult worships a god like insanity inspiring Xenos and/or Chaos God from the dark regions of space. The Cyclopean Ruins of its underwater prison contain all manner of valuable artifacts.
