Star Wars actually has their own 'flood'. It's called the Rakghoul plague.

Assuming the Rakghoul plague is anywhere even close to the level of complexity, intelligence, virility and lethality of the Flood. Flood would murder stomp the Rhakgoul. Let's not forget that a cure or at least vaccine exists against the Rakghoul. The Flood has none.

This is true

Yet all the forerunners have to do is activate a halo ring

Well, actually if Star Wars took over the ark, they would win.

They wouldn't know how to activate the ring
-
They have droids to figure that out and so long as they are on the ark, halo loses it's fail safe.

Flood Kamikaze Armageddon

Exactly. There's no beating Halo. Either halo wins or it's a tie.
