Unless I’m mistaken, I don’t think this would work.

In the example Alex gave, none of the two profiles specifies
GUILE_LOAD_PATH if taken individually.  This example is also in the
manual to illustrate the use of multiple -p flags with --search-paths
(info "(guix) Invoking guix package").

Thoughts?
