@Commdor they have 50,000 years, I'm sure they could solve the drive core problem.

How would reverse-using the Citadel relay wake the Reapers? I do not recall that being mentioned.

Again, Reaper central is not in the middle of nowhere, it's on the edge of batarian space, so close in fact that the Reapers would arrive at the Alpha relay in a few weeks (assuming Arrival take place even that far away from Mass Effect 2's ending).
