I'm on mobile, so I'll give you a better answer soon, but I built a system around this exact idea:
<https://guix-hosting.com/docs/tuto/getting-started.html> And I have ported it to home configurations <https://gitlab.com/edouardklein/guix/-/blob/beaverlabs/beaver/home.scm?ref_type=heads> You can poke around these links to get an idea, but i will write something better soon, sorry about the quick answer now.
