Fan Casting What if Dozier and Donner directed Batman Vs. Superman? in myFiction

What if, during the last few years of William Dozier's life, Richard Donner tells him to revive Batman '66 for a whole new generation of 90's kids after seeing the success of the new Batman film, but, Donner, after seeing the mixed to negative reviews of the last two Superman films, stopped directing superhero films as a whole, and was more focused on Lethal Weapon, but, Dozier, not wanting to give up, saw the potential in a new Superman, and told him, what would happen if Batman and Superman met, and got into a huge fight? Donner still refused to direct the film, until over two years later in 1990, Dozier came back with a sackload of cash, after pitching the big crossover of the 90's to Warner Bros, and told Donner to put Lethal Weapon 3 on hold, because they are making another Batman and Superman movie!
