Three Spirits skin line (Christmas themed skins)

How about three skins based on the three spirits from A Christmas Carol? Please note that I'm not giving a lot of specific details of how these would look since the three spirits have lots of different interpretations and everyone might have their own ideas, I'm just talking about who I think would work well.

Ghost of Christmas Past could be Janna. At first I thought Lulu would be best but she already has an SS (Snowdown Showdown) skin, then I thought maybe one of the other female yordles but Tristana also has an SS skin, and Poppy will be getting a visual update and this kind of skins would require a lot of work. But Janna is also a good fit for a lot of depictions of the Ghost of Christmas Past.

Ghost of Christmas Present. Sion. Now a lot of people would think Gragas, but once again we run into the issue of Gragas already having an SS skin. Plus, the Ghost of Christmas Present is often times depicted less as just a big man and more as a really tall man, and Sion is great for that in terms of size. Plus, it would be kind of funny given Sion's personality and would be a good skin to kick off his new model. Riot could even come up with an interesting design for his weapon to be a cross between an axe and a torch.

Ghost of Christmas Yet to Come. At first you'd think to go with Karthus, but that seems a bit too obvious, plus Karthus has a similar skin to usual depictions of the Ghost of Christmas Yet to Come, Reaper Karthus. But then I thought of a champion that would fit even better, Yorick. Yorick works really well because of how he's a grave digger and the big moment with the Ghost of Christmas Yet to Come is in front of Scrooge's grave. Or we could go with Rammus, since all he says is OK, so the whole not speaking bit could be filled by him.

I also thought about maybe a fourth skin that would be for Scrooge, but I'm not sure who to use for that since the most obvious pick would be Zilean but, once again, he already has an SS skin. I mean, we could go with Vlad, for his white hair and general dislike of people. Trundle, because trolls are said to be greedy and it would be hilarious to see Trundle dressed as Scrooge. Shaco, because he has the nose for it, Gangplank, Thresh, it's a tough one for me to think of.

So what do you guys think? Think this would be a cool skin line? And any suggestions for who you think would work best for each role?
