First of all, sorry for bad English as I am not a native English speaker.
Just watched Warriors animation made for Worlds 2014, and realised the animated loading screen is implemented. I guess Riot was thinking to do it tho, but it never came up. It would be pretty cool tho, and wouldn't be that hard to make it happen as well. Most champions have their own client login screen, and all they need to do is to crop and put it up.
Will that be possible, Riot?
