Ok so how about this then:Supposing of course that I.T. is true, Shepard wakes up back in London and the Reapers are still going at it in full force, and oh noes the Crucible isn't working, or possibly just hasn't reached the Citadel yet.
Shepard somehow learns (possibly through TIM, from where ever he is/was when not in the Citadel sequence) that Omega is involved, the key to their missing puzzle.
Off we go to Omega, en route we rendezvous with Aria who conveniently escaped the Citadel before it moved, becomes our temporary party member as we battle through Omega (fighting Cerberus who are now 100% under Reaper control) and hook up the Crucible/find Omegas' secret control room or w/e, inc superweapon vs Reapers.
EDIT: Oh and Harbinger learns of this and follows Shepard to Omgea, assumes control of Cerberus troops throughout the mission, all the while talking his usual smack, and we get an epic fight with him at the end naturally.
Just spitballing here, but thought of this when I was brushing my teeth and had to jot it down.
