Maybe the quarians would end up discovering Sovereign on the edge of the Perseus Veil and become indoctrinated, then carry out the whole "attack the Citadel" plan. Or the Reapers might get tired of waiting out in dark space for Sovereign to start things up and just cruise back to the galaxy the long way. If you think about it, there doesn't seem to have been much standing in the Reapers' way, even if you remove the geth from the equation.
