What's the best way to test mainline Ubuntu without destroying my Kubuntu install?

Not stupid at all.  It will add a new one to the boot list.  The
default will be the new one and the original will be an option.  To
put the default back to the original (with the new one an option) boot
into the original and run
sudo grub-install /dev/sda   # assuming that sda is the boot drive
sudo update-grub
