A random idea I had a while ago:
What if, in these clan servers, one was able to make a party, a permanent party, which you could add members of your clan to. Leaders could move the clan from server to server, and help anybody in the clan servers.
Then, after a player dies, he is only able to spectate from the POV - the new perspective system that 1.8 brought us, that his own clan sees. This type of spectating system is the one CS:GO utilizes, and I think it would be a perfect use - finally, instead of spectators being disallowed, you would be able to see the point of view of ONLY the members in your clan.
Additional ideas:
Clan battle servers would have an option to start the battle, similar to how mineplex functions, in which the captains can chose things like: First to 5 or 3, 6v6 or 8v8, Scrim or Battle, etc.
Something like this:

The servers would count the score in the battle, and a command would register a DQ, if both captains of the battle agreed upon it, or a clan staff member forced it.
Clan battle servers would obviously only have the clan battle maps that suggested by Soul's or Dave's rules (Most likely Dave's Because that is the clan staff)
