Re: gdm desktop selector
As far as I know, what you want is not possible, it's a corner case.
I think your best bet is to have a first run script that does the needed setup then deletes itself. It would be a simple script that just pops up a modal dialog window with available desktop choices, once the user makes a selection, it's written to .dmrc and X is restarted.
I would make the default GNOME desktop empty aside from wallpaper then place my script in ~/.config/autostart, if GNOME was selected then I could simply load a normal profile before restarting X.
Edit - Sorry, my suggestion assumes the use of autologin or timed login.
