No. But...
This package contains packages from GNOME3 and their dependencies so
they can be used in Ubuntu 11.04 (Natty). This PPA is EXPERIMENTAL and
MAY BREAK YOUR SYSTEM. There is no downgrade process.

That also lists all the packages installed. You could put the ones that
you have installed (minus the gnome3 ones) into gedit and use that to do
one large $ sudo apt-get install --reinstall <package1> <package2> for
the packages you currently have installed. But not sure if that will fix
everything, but certainly worth a try.

gnome-panel isn't installed by default in natty.

You could try an in-place reinstall; meaning you reinstall but _don't_
allow the install to format. That will leave your /home and /opt folders
