I just tried doing that to create the bind mount at /gnu/store via fstab, and it disappeared on reboot (and threw me into an emergency console). Removing the fstab line allowed me to boot normally again. I think the solution will require using systemd to recreate that folder on boot, and do it early enough to not make the system panic like that. Maybe that's a bad idea, I don't know enough about ostree/silverblue. However, after some more digging it seems like this solution would be preferable to changing the default guix store with a custom build, since doing that means you can't use any of the pre-compiled binary packages from the official guix servers.
