Why no crossover with the Incredible Hulk TV show?
both were on CBS in the late 1970s. Both had superhero themes.
You had Wonder Woman and the Hulk. WW is a mainstream, beloved superhero. The Hulk is a misunderstood monster, wanted by the police (and journalist McGee).
Diana Prince works for the IADC government agency; maybe David Banner could have had a temp job for the agency, or somewhere else, where there ended up being problems with criminals, spies or terrorists, and the Hulk ended up wrecking some things which gets Wonder Woman's attention.
The Hulk and Wonder Woman could team up against the bad guys, and then once Diana saw that the Hulk turns out to be David, then maybe she would secretly help him escape. She may also decide to give him a sample of spring water from Paradise Island, which hopefully would help him find a cure.
