Hey, but why do you think about Imperium only?

Orks have great numbers, powerful industry (who else can build working super-heavy vehicle using scrap-metal and pure faith). They are basically fungi so it's difficult to ultimately purge planet of them. A new-born (produced by fungus) okr is already is tough opponent. So for orks it is completely enough to infest a couple of inhabited worlds and grow there population to become a constant threat to the Galactic Empire/Republic or whatever exists in Star Wars universe.

Power of Chaos is not in number of crazy Chaos Cultists and Space Marines (but it is important, too), but in ability to destroy a society from inside. And there is no Inquisition equivalent in Star Wars, so nobody will be aware of another religious group until it will too late. Of cource, I agree that Inquisition is very inefficient, but it exists and works at least.

The least bet in war is on Tau: they have similar technologies and outnumbered by Star Wars forces. But Tau can integrate peacefully to the Galaxy of Star Wars and then dominate polically.

Eldar? I do not like both kinds of Eldar so let me skip to ultimate Mary Sues.

Necrons. Their technology is so advanced that look like magic. Their numbers are countless. And the pie on cake, they can not even be ultiately destroyed. So, basically, they can stomp anything in Star Wars univerce having both technology and numbers on their side. Of course, Necrons are slow, but they have the eternity to complete what planned.

And last, Tyranids. If Leviathan is the largest Hive Fleet then the Galactic Empire/Republic or whatever exists in Star Wars universe has good chances to starve Tyranids to death. But if Leviathan is only one of many scout Hive Fleets then, well, Star Wars setting is over when main Hive Fleet will arrive.
