Depends on your intentions. If you are trying to parody CNN, go with your funny bone.
If this is supposed to be a serious attempt to relate news, copy no one and lose the Saturday morning cartoons. Go full professional.

Gotta consider your target audience and give them a visual and branding package that conveys the intended message. Who will trust Pepe giving the news? Who will trust an obvious CNN reference in the branding? When you have your answer to those questions , you will know your answer on whether or not this works for your target audience.
