Ravenloft in Space!

Actually, the first thing that came to my mind when the OP said "Ravenloft in space" was this.

There's also an older, bespoke, Luther Arkwright game (out of print now, though I believe the IP owner was still selling NOS a few years ago).

That was one book I always wanted to purchase and years later I bought one at Dragonmeet. I learned from the seller that it was from the original print run and he still had a box of them remaining.

I guess he was from 23rd Parallel Games.

I don´t know it this is exactly what you are looking for, but we released a crossover between Ravenloft and Spelljammer on DMSGuild, called Dread Space. It consists in 10 space themed domains for Ravenloft.
