Castle Clan Achievements/Challenges!!!

Well,before all,im Bodi_03,hi,im new,and i just came for one thing:to purpose clan castle achievements.
-Whats it?we got clan levels,spells,troops,wars,etc...but a feature that ill really like and i think it could fix this crisis times with the update....Consists into a programated(like a leader begins a clam war)collective achievement ,that in the end,will give a price to each player,based(or not) how much did he apply/help for the castle achievement.I got this idea from a rol game.
-How would it work?All the players in the clan will participate on it.Eg:Leader enters into clan achievements and sees 3 clan achievements,he should just select one.This achievements are changing every 24 hours.The leader selects 'Friendly clan-Donate all members a total of 5000 troops in 24 hours'(variable for quantity of members,like 25-30 5000 troops,30-35 5500 troops,etc...And any achievement needs to have a dificculty to select(eg:22 people,middle is 4500 troops,easy 2500 and hard 5500),obviously,bigger difficulty,bugger prizes)all members work on it and finally a big prize is given(de,elixir,gold,gems,xp,clan exp,etc..just one of those(or combinated),like in befores example,22 people,final prize is 100000 elixir to share=if a member donates 1% of those 4500,he will get 1% of the prize,if the achievement(or challenge)is ended(the people donate their 4500 troops)in 24 hours.If not,there will be a 5 day pause/penlise/penalisasion(without having challenges 5 days)There could be combined challenges,like:donate 4500 troops and get 100 stars in multiplayer battles(remember,25 member=4 each)and a final prize of 200 gems in this case.
-Ideas:donate troops,get x stars,destroy x y buildings,get x resources...etc..
Thanks for your attention
