But would it be bigger? There were incredible civilizations, hostile civilizations, that were wiped out by the Imperium before they could expand, who were much more powerful than the Interex. I think the Interex becoming bigger would not be likely to happen, they were fairly peaceful and did not conquer. In a hostile galaxy, there is nothing but conquest as an option.

As for the advantage, that depends on how you see it. We saw how easily the Interex were beaten by the Luna Wolves. How would they fare against the modern Imperium? The modern Imperium is superior in military power to the legion days, not because of superior tech, but superior numbers. Throw enough men at it and it will die, and that's where the Imperium always wins, except for the Orks and Tyranids.
