Ideas for possible upcoming Zac Skin

So I have checked out the new Guardian of the Sand skins for Rammus, Skarner, and Xerath, and thought, 'Oh, it'll be cool if they added a Guardian or the Sand Zac skin.' With the particles I saw for the other champions, I can imagine it looking pretty cool on Zac, making him all sandy and whatnot. But normally when Riot makes a skin trend like this they include all positions that could be filled on SR. And this trend is missing an adc, which might be Kog'maw. Idk, just throwing out thoughts. But with summer coming up do you think that they would come out with the skin showing Zac in swimming trunks in Renekton's Pool Party Splash? And just call the skin something else other than 'Pool Party Zac'. Or for winter, they introduce something like Snowman Zac? I know alot of people having been looking for a Zac skin, myself included, and I know Riot can't have forgotten about him with so many requests. But it would be really nice if we could get something. I bought Zac's bundle, but I find myself using the original skin more because it's better than Special Weapon, imo. I like Zac as a champion, but it would be nice to further enjoy my play with him using fun skins.
