@ Raymorn's first post, It could be possible that all the species that assisted in retaking Earth could reverse engineer the Reapers' FTL drives. Assuming that the destory option also destroyed any component of a Reaper to indoctrinate, it would be very practical to execute and implement. Now assuming that the destory option didn't destroy any component of a Reaper to indoctrinate, it would be extremely dangerous and given the effects observed, even on the derelict Reaper that was dead, all the species would assume it would still indoctrinate them and most likely destroy it.

Another problem would be Eezo. Is there enough Eezo to get the species of aliens that cannot survive on Earth to another system where they can flourish?
