I wanted the ending where my Shepard is thought dead by the galaxy at large, while he is found, resuscitated, and brought back to health by Miranda and a team of ex-Cerberus agents who would lay the groundwork for the new Cerberus-like group in the galaxy that Shepard and Miranda would be forming, with the purpose of getting a monopoly on Reaper tech and giving humanity a special advantage while becoming the hidden puppet controller behind the alliance and new galactic government to forward his own agenda. Eventually, we'll hit a point where the singularity is once again possible and it will be enacted with separate means than that of the Catalyst. People like Petrovsky, ex-Cerberus agents and scientists, and the Shadow Broker network (brought under Shepard's control after removing Liara) would be the framework for this organization. They do have external, alien agents as well.
