What If WWE WrestleMania Was Always 2 Nights?
32. WrestleMania 4

WrestleMania IV is an interesting case, as most of the event is comprised of a tournament to crown a new WWF champion.
Hercules against The Ultimate Warrior in a generic singles match wasn't strong enough to headline, nor Brutus Beefcake beating The Honky Tonk Man by disqualification for the Intercontinental Championship—though WWE could have possibly considered a title change there if that had been the case.
Demolition's tag title win from Strike Force and the opening battle royal also seem like strange main events, which means the tournament itself would have to be the focal point.
In all likelihood, WWE could have probably changed the layout of the tournament, but since that's too speculative, it's a safer bet to just say Hulk Hogan vs. Andre the Giant would have been the last quarter-final match of the night. Ending in a double-disqualification makes for an odd finish to night one, but since it leads directly into the next night, there's a way to book it where it acts more as a cliffhanger than a disappointing ending to that match.
Night two would have been the semi-finals and finals, as well as all the non-tournament matches, still ending with Savage beating Ted DiBiase.
