Like the idea of the bunny, the 650 HP pretty much makes it a light and fast tank, but I feel like certain defenses do extra damage to the troop like a small bomb, like the way the giant bomb does more damage to the hogs, the smaller bombs might possibly disorients the bunny making it stop in its tracks and causing it to take a bit more damage from point defenses. Also I feel like splash damage defenses like wizard towers do less damage to the bunny.
Sorry but to me this just sounds like a big valk that jumps over walls like a hog and takes up more space a lot of the numbers are about the same as a valks
