Deploy SLS ZIP file for ClojureScript project to S3 using Leiningen

I have a ClojureScript project (NodeJS) that uses Leiningen for builds. This works with Serverless via a plugin. The SLS plugin invokes a Leiningen plugin that ultimately compiles ClojureScript to JavaScript after which SLS takes over to create the ZIP and CloudFormation stack files. Leiningen is similar to Maven and used to compile, test, manage dependencies, and cut releases. I know this is a bit of a niche use case (seriously how many people are actually using SLS and ClojureScript) but was wondering if somebody found a way to use Leiningen and SLS together to deploy the SLS created ZIP to a Leiningen configured repository?
