Fan Skin concepts left to rot- what fan skins should riot make happen

As the title might suggest, the boards have seen fan skins come and gone, but we here in the LoL community never forget. We've seen several design concepts that still could make it as a official skin. What fan skin would you like riot to possibly consider?

For me, I still aim for my sandwich king trundle idea from years back where Trundle would be a sandwich maker. Possibly wearing a apron and using a actual sandwich club as his main weapon. Basically a food joke skin. Something I thought would fit Trundle very well. I even had an idea going back that his dance could be changed to the promotional "5 dollar footlong" dance subway had put out.

I also had ideas similar to spider amumu, only it would play more off super teemo and that amumu would be something like a forgotten sidekick. Teemo would get all the glory and amumu would be the one no one pays attention to. His q could be replaced with a grappling hook, his w could maybe be like a oil slick (dating back to older gag superhero comics) and never thought much about his e or ult. Here again it's a concept i kept more to myself because people were very dead set on the whole spider amumu idea.

Is there any skin ideas you had or maybe past board posts you thought would make great ideas?
