It should be possible to add them to the update repository. It's not the normal way and therefore might need more discussion but I doubt it's impossible. Btw. I would first push the packages to openSUSE:Factory,
If you want to take the version that's currently in GNOME:Apps, the only additional requirement I think is python-markupsafe which has been pushed to oS:F anyway in preparation for 11.4.
Has the GNOME:Apps version been pushed to oS:F?
