The quirks in My Hero Academia are often very physical and unique to each individual. In a crossover, Uraraka's zero - gravity quirk could be used in space battles in the Star Wars universe. She could disable enemy ships by making them weightless. On the other hand, the Force abilities in Star Wars, like mind control and precognition, could give the My Hero Academia characters an edge in combat. For example, Todoroki could use his ice quirk in combination with a Jedi's precognitive ability to anticipate his opponents' moves and freeze them in place before they can act.
Well, consider All Might's super strength. In the Star Wars universe, it could be compared to the brute strength of a Wookiee. But what if his strength was also related to the Force? Maybe he could use the Force to enhance his already massive power. And then there are the more esoteric quirks like Hagakure's invisibility. In Star Wars, this could be seen as a form of stealth technology or a Jedi mind trick on a larger scale. The characters would have to learn to adapt and use their abilities in new ways in this crossover scenario.
