Since you all know when a team/clan/faction plays 12 man the common thing is to have one person to be Drop Commander and usually he is piloting an Atlas (and since atlas has option of mounting command console there is where I got my idea in the first place) and he is charged for organizing people in lances, overlaying tactics, planning mech movement on map and fighting/tanking damage. Now I'm sure you will agree with me that this is a bit too much for one person alone to do. So I had the idea that when you equip your command console you are enabling one more person to start the game with you in group options he would have special place and would be visually different from the rest of the group. Two reasons for this, he is connected to command console and he isn't piloting a mech. That 13th person would be in charge of commanding all 3 lances in a similar way as we can see in intro of mech commander (for reference you can see this link : http://www.youtube.com/watch?v=2MQPWE_M_EM; although I'm convinced that you already know what I'm talking about).
He would start with map overview and possibly 12 small windows (with names above/bellow each) so he can quickly shuffle through pilots and get better idea of what is happening on battlefield via cockpit view. This could allow faster reaction time of players in forming more coherent actions and giving your DC opportunity to see the issue with his own eyes (and not to try to bang his head on desk on other side of map). Also he can by point and click method on map make routs for mechs/lances. Although for this it should need to have lances in three colors to make some diversity, you can use e.g. blue (navy) for single pilot, green for one lance, purple for second and orange for third, these are only suggestion and can be changed in the manner you see them suited. Possible colors or map pointers can be added for UAV, Arty/Air strikes. (see picture below for reference, was quick photoshop play but its visible enough)
Some of this is already outlined in detail in sarna, http://www.sarna.net/wiki/Cockpit_Command_Console , and this part " A Command Console is a BattleMech component that can only be added to Heavy or Assault class 'Mechs" can possibly can be reworked to have all of them or at least one variant per chassis, so this way we are getting balanced option and much needed diversity.

As a competitive player I can say that it would be helpful to have one person looking at the map, processing info from scouts and giving order for lances to move. In current game its hard piloting assault, tanking, and DCing all in one. Also I believe this implementation would benefit usage of UAV/Artillery & Air strikes, since now you will have one person who's not worried about taking, damage output, position and so on, and can solely devote himself to information processing. Also this could bring competitive play on new level, giving the game some tactical depth, a bit more interesting approach and one feature that could help people become more organized since after all this is a team based game. And its shame to have item sitting in our inventory without any usable value.
