It certainly won't be enough for RPM. There needs to be a libblas.so pointing to a library with SONAME libblas.so.3, same for lapack.

The current packaging in Fedora is horrible. Thinking again, we had this discussion over 3 years ago: https://pagure.io/packaging-committee/issue/352 and another one starting 2 years ago: https://pagure.io/packaging-committee/issue/588 which is stalled because Orion doesn't have any time lately. I'd love to see this done properly, but I don't have enough time to work on this alone. Are you volunteering to patch all blas/lapack implementations in Fedora to provide drop-in replacements for each other and address all the issues mentioned in the above tickets? I would support such effort and would certainly lend a hand. It'd definitely be a much more productive use of your time than complaining here.
