I play and run Torg, both with and without the original system. I've done a broad variety of alternate settings and cosms, and often I just import other games to serve as my settings. One of my favorites and most memorable was a Torg / Feng Shui mashup that combined settings from Earthdawn, 7th Sea, Spycraft, Shadowrun, and Fading Suns. Each cosm was its own reality, with Core Earth also serving as the Netherworld from Feng Shui. Each of the cosms was, at least in theory, chronologically related to each other, and the through-line of the plot was the encroaching horrors from another dimension.
