It's not just gsettings but other things like different lightdm user name on iso, mime-types, overrides in /etc, /use/share etc and unity itself may not be the right place for all of it. That's what other desktop-sessions does, mate has mate-session, budgie has lots tweaks & overrides (https://github.com/UbuntuBudgie/budgie-desktop-environment). I actually created that package because Budgie-dev and Martin Wimpress recommended such.
