Why this is not enough for your use case?  As mentioned in [1].

The closing message says:

        Yes, this does work.  Combined with the fact that it is now
        possible to "guix pull" channels over SSH, there is no need for
        this patch any more.  The "git-checkout" gexp-compiler basically
        does the same thing that I was trying to do (it is still
        "impure" in that the fetching happens outside the store), but it
        does it more elegantly.

so instead of…

…maybe the location is “git-checkout” gexp-compiler and see what is
missing for covering your use-case.
