I dont quite think I'm reading for such a project, I mena all I can do is skin. Very basic coding skills are all I have. I will happily have a shot at creating a mod that added Hero units to the game though, heres a rough idea.
Each side starts with the choice of 3 Hero units, as the battle goes on the player has the choice of upgrading that unit. Based loosely on the Generals (Airforce, Warlord etc), each unit would specialise in a different area of combat. A new building would be added to each side in order to allow the A10 Strike, EMP etc to still be used. Here is an example of one of the units:
Special Agent Archer -
At level 1, Special Agent Archer is armed with only a slienced pistol. As he gains experience he is able to choose from stealth upgrades, demolition charges or the ability to steal resources from the enemy. When he reaches his final level ( 5 ) he can call in an A10 Strike.
I realise this sounds a bit powerful, but remember that each faction will only be able to have one of these units in a battle.
This idea may be a complete flop, but with the input/ideas of the community I could perhaps finalise the concept and put it into action
