That should work, in theory. You may have to clear your site cache to make sure that the updated LESS gets rebuilt to CSS. To do that in Concrete 5, go to the dashboard, then System & Settings, and under Optimization go into Clear Cache and click the Clear Cache button. I hope that helps.
I'm assuming you're working on a dev site and not a live site, but any time you are making changes like this I always recommend taking a backup first.
