How about this? The protagonist is an agent for Liara/shadow broker, with the task of investigating some new threat to the galaxy, or to maintain the peace that was created as a result of the Reaper war (e.g preventing wars from breaking out in something like a Cold War scenario). This would give a lot of chances to bring back at least 1 old character (since Liara/Shadow Broker is only just over 100 in the ME trilogy), even if the new game is set a few hundred years after ME3, while providing many opportunities to introduce new characters.However, note that if this is the case, then the new game would have a very similar feel to the original ME series (being a high ranking/skilled "agent" with an important mission), which may or may not be a bad thing.
