Don't know if this meets your requirements exactly, but it's certainly
possible to do this manually.  Split your drive into multiple
partitions.  Use one for /boot that will be shared across all installs.
Create a partition for each Ubuntu version.  Then copy a relevant menu
entry from /boot/grub/grub.cnf to /etc/grub.d/40_custom, modified to set
the root= param for each to point to the two partitions, and re-run
update-grub.

There's probably half a dozen other ways of doing it...
