Hidden Immunity Idol Twist

So this week's question. Is is just me or does it seem that there really isn't much effort being put into hiding the hidden immuniuty idol on Survivor? I think 19 of the last 20 idols was hidden where? In a hole in a tree. When people can find the idol without a clue or with a clue and having to spend about five minutes finding it, doens't that send a message? I think my eight year old nephew could find it in about five minutes because all he would do is go up to the first tree and start looking in the holes. Come on guys, how about a little effort.
So along with complaining, here is my idea to put a unique twist to the game. Since there are usually 16 - 20 players per season, simply give each and every player a clue at the beginning of the game to the whereabouts of their individual piece of an idol is located. The difference would be this, there would be identical pieces which would be put together to form four/five idols and each person would be looking for a piece of an idol. Each idol would consist of four pieces and the players would have to find players that have the other three pieces to form one idol. The idol only works if all four pieces of the idol are put together. This could be a great way to form alliances and once again make a unique twist to this game. Once an idol is put together, who gets to use the idol? You might have a group of four people come together that might not have formed an alliance in the first place.
