If CBS does make a Star trek cartoon in the future, who should be in the voice cast for this cartoon? Should it be just veteran Star trek actors or should they also hire professional voice actors, like Frank Welker and Jennifer Hale?
Sure, and you can have Peter Cullen play the captain, and Frank Welker can play the evil Klingon captain, and their crews get into a fight aboard the same ship and it crash lands on an alien planet where all the life forms are machines...
Kidding. The answer to your query is "Yes." What's going to happen is what's been happening in cartoons for years now. The cast will be a mix of veteran voice actors, traditional actors new to voice acting and traditional actors with a lot of experience voice acting.
Several veteran trek actors fall into all of these categories. Even if the animators don't go back to the well and use known characters the veteran trek actors can still be part of the cast.
