Maybe have it so the Goa'uld can give extra income, the Asgard extra defence, the Replicators extra covert, and the Tauri extra attack.
Otherwise it would give the Asgard a very big advantage....but on the plus side it would encourage people to build up their defences as a commander rather than hid in the lower ranks.
