I think the Empire would have a bit of a fight against the Reapers. They would utterly dominate the Citadel races, but the Reapers would give them a run for their money.

I think that the Reapers would be able to wipe out the Imperial navy in a space-battle as they have the numbers advantage. I personally feel that kinetic barriers would work against Star Wars energy weapons, and that Star Wars shields would work against Mass Accelerators. The advantage the Reapers would have here is that they are able to go up close and personal (ramming), where the Star Destroyers can't.

But I can't say anything for certain as both sides use massively different technology and tactics. Also the universes have different laws of physics (Star Wars tech won't work in ME universe, ME tech won't work in Star Wars universe).
