I don't really see the need for a Compass version right now, but you can try to port it anytime. It'll be easy, since Gridless doesn't have any pre-made grid systems or classes.
I'm a Compass contributor and lover and I'm working on a framework which will provide the ultimate set of tools for front-end engineers.
Currently it's still undocumented and there are no examples; the project will gradually grow after I find some time to write some tests, but you can check it out here: https://github.com/kuroir/Survival-Kit
Survival Kit is to Compass(SASS) what Rails is to Ruby(Core-Library).
