I agree with this. I have never done a full Debian -> Ubuntu or
Ubuntu -> Debian transition, but I have often pulled in one or two
packages from the other distro.

My main machine is currently Sid, with Gnome, GTK and hplip
packages from Ubuntu's dev version. In the past I have installed
large numbers of packages from Ubuntu, and then gradually
moved back to pure Debian as the Debian packages caught up
or passed the Ubuntu versions.

You have to know what you are doing regarding resolving
dependency conflicts (aptitude's ncurses interface being
invaluable for this), but it is definitely possible.
