I like your wallpaper/grub/bootsplash/GDM-theme.
What's about a KDM-Theme?
I have never done a kdm theme before...if its as simple as making a gdm theme I will look into it tomorrow...
There is a feature request for incorporating official arch-style GDM/Gnome theme (KDE and Xfce already have this).
It would be nice if someone with good graphic skills can do a single arch theme for all gnome-related stuff, or extend one of already available. So it can be made official.

Gnome Splash is on its way
