yes, it's possible, I think. you could probably just install litestep, don't set it as the shell, and configure a theme that DOES NOT USE A DESKTOP MODULE. if you forget this, it WILL cause problems. then just configure the theme. you may also want to include LSNoShellWarning (though I'm not sure if it's still included in the latest builds) so you don't get a warning when you start litestep.exe
