I know it is a little early to talk about this but what ever. I think it would be awesome if RIOT created Christmas Carol skins next season! With 
or 
as the ghost of christmas past, 
as the ghost of christmas present, and 
or 
as ghost of christmas future. You could also include tiny Tim 
(with a crutch instead of a trident) and even 
as Scrooge! Man would these skins be weird or what!
It is a good idea but I believe Zilean and Gragas both already have Christmas skins and it seems rather ridiculous to give them another one instead of others champions.
Anything besides that the Idea seems really nice for this year Christmas. :)
Riot could also do some more Nutcracker themed skins, other than Nutcracko Shaco (I think it's called that). This year's were mainly just frosty and blue, but skins twisted off more Christmas tales and songs would be nice. (Like Silent Night Sona, Slay Belle Katarina, and ReGifted Amumu etc)
That would certainly be worth using in your portfolio to apply for a job in Riot ^_^
I'd think it would be cool if 
got one.
How about Christmas Morning Annie? Where she is dressed and looks like she woke up on Christmas Morning, with her backing animation as her falling asleep on her bed with a sleigh and reindeer flying above her or like making a snowman, or opening presents under a tree.
I like Jingle Bells Syndra. She throws little bells and wears a christmas outfit. lol
Please get me a cute Christmas Orianna skin! Like a dancer in The Nutcracker or something! Or Maybe a caroler!
I <3
