The biggest problem for this is that two of the "playable" races could be on the verge of extinction after the events of the Mass Effect series. It would require a "canonical" path for Commander Shepard to have made so that they don't condemn the krogan and quarians to extinction, which would take away an important aspect of the Mass Effect series.
