Current versions of GRUB should read past versions of GRUB2 going back to 1.97 using configfile. And it can read GRUB legacy (0.97) grub.conf files using legacy_configfile.

If the distribution with the newest version of GRUB has grub2-install run, such that the grub core.img and *.mod files it loads are also current, you shouldn't have an issue using just that copy of grub and loading the various grub.cfg or grub.conf files. If you do, it's a bug and should be fixed rather than coming up with Rube Goldberg methods of booting the computer.
