Agreed - if the money was right I am sure most of the TOS crew would come back. That being said - I don't think there would much interest in bringing TOS crew back. I see having an animated nuTrek crew series with the current actors voicing their parts - if the money was right being a better option. In between the major motion pictures, I would think that they could voice their roles for a whole season in a pretty short amount of time which would also be appealing.
