Integrating Relume into an Existing Webflow Site: Tips Needed

I am taking over a Webflow site from another developer and want to use Relume. Anybody incorporated Relume into their workflow on a site that doesn't use Relume components/functions already? I would love to restart the site using Relume, but that's not in the cards right now. I would also love to rename the classes but not sure that's the best idea either. Any help would be appreciated!
