i think so, at least for team attack boost. I would think 4 7 stars and a 6 star with an attack boost active (from the 6 star) would do more damage than 5 7 stars without an attack boost. There are different kinds of passives, but I guess if you can clear whatever quest comfortably without some passive, then you could replace that passive-using unit.

passives are worth it, but still pay attention to your attack skills.
