Since reproducible builds are a goal of Guix, as far as I know, maybe it would make sense to only do solution A, and only do it for packages which are reproducible.

That would provide extra motivation for fixing non reproducible packages, and would also prevent having to do a bunch of work for use cases that are not the final goal.
