Login screen suggestion

I think it'd be awesome if we got to select which login screen to use. There could be a customization setting on the login screen page, where it displays all the choices. I'd personally love to keep the URF one as my login screen (I think it's super epic!) To go a further bit into the idea, after clicking the login screen customization setting button, it'd display a little thumbnail for each login screen, and when you click it, it gives you a preview of what it'd be like (music and animation), then you apply it and it saves. It's just an idea I thought about, feedback is appreciated!

Thanks
