In my newby opinion, when I want higher-tech I drive my Jaguar XKR, or XJR, both of which are higher-tech than my Viper. Or my trusty old XJS, which although lower-tech than the XKR, is higher-tech than my Viper. But that misses the point entirely, the Viper is for fun! Likewise I could buy a power boat, but I prefer my sailboat. Talk about low-tech - sailboats are really old-tech. Even the carbon-fiber/kevlar race boats still use sails, which were invented eon's before cars were even a pipe dream. To me the Viper is a pure, honest car, no electronic (synthetic)handling, traction control etc. (with the exception of ABS), it's about having fun. If people want to modify their cars, feel free, that's part of the fun. I don't think anyone would put a Paxton or turbo on a Ferrari or Lambo, they appeal to a different crowd.
As to whether a paddle shift would out-perform the current stick, that would largely depend upon the engineering resources that were applied to the task, and the skill level of the drivers. If it was a one-off design, I really wouldn't expect stellar performance, but people surprise me all the time.
