The people are actually quite easy to replace since you can kill them, it forces BioWare to double up on dialogue in case you railroaded some characters straight to the graveyard in ME1. They have to do it anyway in-game (because you kill some characters or take different ones on missions) so that shouldn't be too hard to add a little extra story in case one character is alive or dead.
The council, on the other hand... That changes everything. Maybe if they kept the story stock and just had human models instead of aliens... But that would force every NPC in the game to completely ignore that their gov't just changed. It doesn't make sense.
