Unassigning for now as I don't know if I'll have time to get that done for 17.10.
However, I'll take any good patch from system76 implementing that feature (even better, I really think it should be pushed upstream). The best implementation IMHO is to not hardcode any css files with alternatives, but rather a settings for the gdm user pointing to the system-wide css file to load. Then, distros and OEM can use classic gsettings override to tweak it.
