Could the x11proto packages be audited to see if they really do need to be renamed? They usually stay backwards compatible.

In the set of could probably also die and or probably not needing to be updated:
xauth
xfonts-base
xfonts-utils
xutils-dev
xkb-data
xkb-data-udeb

Which probably leaves core X, some x11 specific server packages and all the input/video drivers.
