I don't think it's just a matter of sharing libraries and system files. This is not just another kernel version, it's an entirely different kernel. A backup might not be enough, and even if it is, keep in mind that every time you decide to switch from Hurd to Linux or vice-versa you will need to restore a backup, which means an intermediate boot to restore the backup before you can boot your system again.
