Dark Elixir Only single player campaign or 'Challenges'

The original single player campaign was designed when Dark Elixir didn't exist.

So, I was thinking that either a single player campaign for Dark Elixir might be a good idea, or a series of maps that we can play weekly might be a good idea. Oh, and for more fun, let the players design the maps and share them in game. Unfortunately, unless it is accepted by supercell, you don't get to keep what you raid in the collectors, but not expending troops during the 'fake' attack would also be nice. (Basically, a 'dark' campaign and let the players help design the maps.
