Would Love too see old skins again!

Everyone enjoys owning rare skins but some no one really has which is alright due to the things people had to do to get them Grey Warwick and Kingpin are such skins, but the skins I am talking about are skins that no one really bought due to the year or popularity, but now people really want to see them again, like Curling or Manatee which is a huge bummer we cant get them anymore, even though now people would be willing to buy them. I think riot should do a one week skin event bring all the old skins back then make them rare forever, except for ones that have limitations such as refer a friend or pre-ordering League of Legends. Charge them for acceptable price and Riot would get a huge pay off the skins and I think this would be a fair trade I would spend like 100 bucks if I saw this lol what are your guys thoughts?
