What if the Sweep repaint is just a lighter blue Scourge in a two pack with a Kup repaint (like RTS Cyclonus/Rodimus). Could make the army building more expensive!

I assume also that many people buying Hasbro Scourge for their sweeps might be using a United Scourge as their prime toy?

The Junkions had completely different looks to Wreck-Gar, but the Sweeps were exact copies so it's not really the same question with the two toys when it comes to army building.
