Looking at [1] and at the libjs-bootswatch spec file, …
I found https://src.fedoraproject.org/rpms/python-XStatic-bootswatch already in the distribution. It looks like it probably already packages the CSS files you need.
I’m not expressing an opinion on whether it correctly deals with the guidelines issues I noted above; I am guessing it might not, but I didn’t read the spec file closely.
