They should make this, but I think they wont do that.
But we from "Republic Commando Reloaded" working on a mod called "ECHO".
A short introducion:
In this mod you are playing "Zero" in the Single Player Campaign, the leader of the Echo-Squad. In this campaign you're playing this character from Kamino over the Clone Wars, over Order66 to the Galactic Civil War. So the second part of the Campaign you are a Imperial Commando, with a Imperial Commando helmet and weapons etc... And your're not a "rebellion-squad". as the other clones, you follow orders. So in the second part you will get missions against the Rebel Aliance and other enemys of the Empire.
