'Linux', or more accurately X, does support transparency, although I'm not sure what you mean by 'replace linux interface for litestep'. LS themes do not transfer, if that's what you're talking about, however, the *nix theming communities are much larger than the LS one... still, moving to another OS is not something you just do in an afternoon. Think about it, read about it, get a friend who has done it _first_.
