I have actually done this a few years back. The trick is to add in the Kubuntu backport repository to get later versions (at least back when I did it).
I called it Kupobop and changed the OS symbol to a tiny moogle from Final Fantasy.
Then my Arch friend annoyed me into trying Arch, so naturally I now use Fedora.
openSUSE is still on my distro bucket list. When I’m ready to hop I usually just start pushing my luck messing with things until my current setup fails. Then I pretend to be upset and inconvenienced while secretly excited to try something new.
