Honestly I don't doubt one bit that when you balance a game for a four men party adding the option for six is going to trivialize things.
And I don't doubt that the game may have a "good flow" with 4 characters, either.
My problem with the small parties is that they hardly allow any composition variety: once you reserve a slot of any major role (i.e. healer, tank, dps, rogue) you are pretty much out of room to personalize and all the alternatives are about sacrificing one of these roles just for the sake of experimentation.
