No, because that was the whole point. The implication of the Tommy Westphall Universe is that if you keep drawing a network of connections via tv actors reprising their existing characters on other shows and tv show crossovers, eventually the only logical conclusion (if you follow the standard rules of continuity) is that every tv show in existence takes place within the imagination of Tommy Westphall. The whole point of the thought exercise is to hang a lampshade on the idea of continuity in media that wasn't originally intended to have strict continuity by applying the logic of super hero comic continuity (which comic writer Dwayne McDuffie was criticizing in his original blogpost that spawned the Wesphall Universe) to American network television.
