Yes. The glaring weakness in the list is Bossk can go down like a ton of bricks under focused fire. I tend to bait my opponent after Boba, and try to use his durability while Bossk stays at R3 with the mangler. Bossk does not like furballs, but Boba thrives in them.
Since I'm more aggressive with Boba than Bossk, I can plan ahead if the opponent decides to go all in on Bossk. With his stop maneuver and surprisingly fast dial+boost I can usually allow Boba to get several free shots while the opponent takes ineffective (R3, through a rock, etc) engagements against Bossk.
Thinking about how it would play, I can see why it works well with the set of upgrades you chose. Fly them up side by side, then on the engagement round Bossk stops (hopefully at range 3) and Boba dives in to range 1. Tough to deal with. And if anyone tries to flank Bossk, he can get out of there with amazing speed -- green 3 plus boost moves him halfway across the board.
