User blog comment:FastLizard4/New Skin and AJAX RC/@comment-140200-20100119034411

I was looking at how Memory Alpha, a wiki that is many times larger than ours, handled having a dark skin like our new one. They didn't bother with classes in the templates, they simply rewrote them to have matching backgrounds and rewrote the CSS files for the alternate skins to have matching themes. I'd be more inclined to do this too, if for no other reason than it is much less work.
