I'd be far more comfortable with that. A final 4 (or 5) of Omega, Metroplex, Trypticon, Scorponok, and Fort Max seems reasonable. Blastoff and cosmos in a final four seems absurd. The likely hood of a minibot being able to harm defensor from such distances seems implausible. I would imagine that defensor would just wait until cosmos ran out of power and had to come back down. How many bombs can cosmos have? How long can he shoot lasers from space? I just can't see defensor being harmed by this, especially with his defensor force shield.
