Nix itself does an easy transformation:
nix-instantiate --eval --strict --json ./lib/licenses.nix

It is a bit verbose though, we could make it shorter:
{"afl21":{"fullName":"Academic Free License","spdxId":"AFL-2.1"},
"amazonsl":{"free":false,"fullName":"Amazon Software License","url":"
http://aws.amazon.com/asl/"}}

Other than the quoted names it seems reasonable.

https://github.com/NixOS/cabal2nix/blob/master/distribution-nixpkgs/src/Distribution/Nixpkgs/Haskell/FromCabal/License.hs

Then you would not need Nixpkgs's license list at all, except for reference.

All licenses that we have are here [1].

[1] https://github.com/NixOS/nixpkgs/blob/master/lib/licenses.nix

I think that code is so simple that with a small transformation it's json,
without using libnix.
