It's rather tricky due to how theme styles are generated dynamically. As far as I know there's no API where you can input a number of configuration values and it will generate the required CSS on the fly, so you'll either need to replicate (and then painstakingly maintain) the SASS that's used to build it all or go with smaller scale changes hooking off the body class as suggested above.
