Exchange idea.

Hi. I have a question. Could you add to the next update the exchange of materials between the members of the clan? This would involve replacing, for example, gold on dark elixir. Mileage exchange would look like this:
1) selecting a member of the clan to which we would like to mention.
2) Select the raw material to the exchange.
3) The other person sets the price for the chosen material.
4) If the first person agrees to the stated price pushes a button and there is an exchange.
In this way, a person with a lot of unnecessary raw material could be replaced with other material which is needed. I am very sorry for the mistakes in words but do not know English well. It's good or bad idea ?

Ruled out.
