that's an interesting idea...
IMHO, the whole idea of gaming the victorian era is that thing about the impact of industrialization on society, in all aspects.
In an exaggerated way, VSF is the bright side of it with the Jules Verne enthusiasm for modernity (tea and cookies anyone?), whereas Steampunk is the dark side. In that setting of thought, there is no need for a lot of additional exaggeration to picture a hell with (OK, underground lava povered steam machines) dirty unhealthy workers operating (or being operated by) machinery.
See Metropolis and Modern Times for inspiration.
In that hell, the army of the Devil would wear period suits or accountants' gear, sometimes having nice "Alice in Wonderland" tea parties in the green, while the others have to work away from the sun
how about that twist?
