It just occurred to me that the last time we saw a Klingon turned into a human, Arne Darvin still maintained a Klingon lifespan and easily lived until Deep Space 9. Would Voq turn out the same way? Or was his lifespan reduced to a human's to fool sensors? I don't think this was ever discussed. In this scenario, it's entirely plausible that Tyler/Voq would be around in the TNG era, or could even show up in the Picard show. They might have to age up Shazad with makeup or get an older actor to portray him though.
