Donating Gold, Elixir, and Dark Elixir

I know an abundance of clasher who think that donating resources to fellow clan members should be implemented into the game. Yet there would be an issue of balancing it out to where low level clan members would not be able to tremendously jump in the rankings and village upgrading. Since every in a clan has a clan castle it would make sense that donating gold, elixir, and dark elixir would be deposited in the castle's storage. The real question is how much and how frequent. Troops can be donated every twenty minutes, unless the clan is a higher level that permits faster request times and there is a cap of housing space based on the level of your clan castle. The guidelines of donate resources should be the recipient should be able to receive 50% of his/her clan castle's max storage and be only able to request donations every twelve hours. And then increase the max percentage and/or decrease the request time by leveling up your clan. This would be a great way to share and increase clan moral. Also with these donations there should be new achievements that correspond with the act of donating your hard earned resources.
