In regards to your comment on governing you said
Now you might have meant otherwise but I assumed that you meant people within the government under the Empire. If so then you have contradicted yourself.I was thinking of some people in government and other positions making contact with dissidents from the SW galaxy itself as well as the Jaffa, Tokra and off course the Asgard and so on.
If the Empire controls the government then the pleas to our allies would almost never make out of the system.
As for self-ruling, the officials chosen would be a generation or two after occupation and the people would be indoctrined by the Empire and no longer hold the values necessary to resist. Proganda can be a very powerful tool if used correctly.
