Sure, you can install it and try it out -

1) Make a directory for your theme under /usr/share/gdm/themes. E.g., 

2) You'll need a GdmGreeterTheme.desktop file, named exactly that, in 
the /usr/share/gdm/themes/awesomefc7-theme directory. It should 
reference the xml file of your actual GDM theme markup. Let's say mine

/usr/share/gdm/themes/awesomefc7-theme directory.

4) Any supporting artwork files (pngs, svgs, etc) should also be dumped 
into the /usr/share/gdm/themes/awesomefc7-theme directory.

file has the correct name and path and all that.

6) Log out of your session. The GDM screen you get should be the one you
