Have you made any progress on this? =)

FYI I also think that that's the best course of action. I remember
dealing with non gnu-build-system packages in nixos was a bit of a
pain, so I was biased against the importer thing. I think guix does a
better job at it...

To build the crates needed to build cargo a good idea is probably to
have rust-build-system take a #:cargo and a #:rustc package. Then you
can pass the binary versions for bootstrapping cargo.
