I am a for V10 Viper engine. For longevity and reliability, I am not a big fan of forced induction but am a big fan of there is no replacement for displacement. This will hopefully help with the economies of scale down for that engine in both cars.
As for taking sales away from the Viper, who cares. If you get an order from a Challenger or Viper at least Chrysler is getting the money instead of GM or Ford or some else.
