Looks good to me.  The same is needed for Grid Engine.  Previously I
would use “env” with an installed profile for the same effect:

--8<---------------cut here---------------start------------->8---
#!/bin/bash

profile=/path/to/.guix-profile
exec /bin/env - PATH=/opt/uge/bin/lx-amd64 \
                SGE_CELL=default \
                SGE_ARCH=lx-amd64 …
                GUIX_LOCPATH=… \
                /bin/bash --init-file "$profile/etc/profile"
--8<---------------cut here---------------end--------------->8---

I guess the only thing that’s missing now is to activate an installed
environment.
