I'd love to see something like what you've described ... though a little differently to how you've described it.
It would be great for a designated commander on each team to be able to see and use all the accumulated information available from all the sensors of all of your team. However, I wouldn't want them to have a privileged 'eye of God' view of the battlefield and enemy. That is, I wouldn't want them to know anything about the enemy that isn't being sensed by a member of his team, as that would be unrealistic. Nor do I want them to have any 'Hand of God' weapons.
How about this:
The designated commander could have access to a special command room in the hangar, which basically contains a big realtime map with all your team's information, and whatever your team is currently sensing about enemy locations, designations and conditions. The map would be interactive, with menu and mouse shortcut commands to enable you to issue your team with instructions and intel.
Further potential enhancements:
* The commander can launch from his hangar a recon probe/drone which cricles above some point on the battlefield of their choosing. The probe would provide radar and visual information, and it would be able to be shot down by the enemy. If it gets shot down, the commander has to build another one, which takes time to manufacture and deploy.
* The commander could send a remotely-controlled robot Mobile Field Base to deploy at a designated point on the map. The MFB would enable basic team repairs, and ammunition reloads. It would have a turret to defend itself when deployed, and would have an exhaustible supply of armour, parts and ammo. Again, it's destructible, and takes time to manufacture and deploy.
I think the above would add a great new dimension to the game. I used to love playing Titan commander on BF2120, directing the team to the latest hotspots of the map, providing supplies as needed, helping them help each other, etc.
