The characters can be incorporated by simply having them show up in the Star Wars galaxy. For example, Thor could land on Tatooine with his lightning powers, causing quite a stir among the locals. His Asgardian technology could be a mystery to the Star Wars characters.
Well, imagine Thanos in the Star Wars universe. He could be a Sith - like figure, trying to gather all the kyber crystals (akin to the Infinity Stones). The Avengers could team up with the Jedi to stop him. The Hulk could be like a Wookiee in terms of his brute strength, and Thor's hammer could be seen as a sort of lightsaber - like weapon in the Star Wars aesthetic. There are so many possibilities for these two universes to collide in fanfiction.
The Avengers Infinity Wars is about Thanos' quest to collect all six Infinity Stones. He believes that by wiping out half of all life in the universe, he can bring balance. The Avengers and their allies try to stop him. There are many battles across different planets. In the end, Thanos manages to get all the stones and snaps his fingers, which causes many beloved characters to turn to dust.
It's highly unlikely. Infinity War was a huge cinematic event with a massive fan following and complex storyline. A solo Star Wars story might have its charm, but it's tough to compete with the scale and impact of Infinity War.
Avengers Infinity War is largely based on the Infinity Gauntlet comic. Many key elements and plot points are drawn from it, but there are also some creative adaptations and additions to make it work for the cinematic universe.
The Power Stone, being a source of immense destructive power, could be a game - changer in Star Wars. It could potentially destroy entire star systems with a single blast. This would force the various factions in Star Wars, like the Galactic Empire or the Rebel Alliance, to either try to obtain it for themselves to gain an upper hand, or to prevent their enemies from getting it. It would introduce a whole new level of threat and power struggle that goes beyond the typical lightsaber battles and political intrigue.
It's a complex and epic tale. Thanos is on a mission to collect all the Infinity Stones to wipe out half of all life in the universe. The Avengers and other heroes unite to try and stop him.
The plot of Avengers: Infinity War involved a massive battle between Thanos and the Avengers. Thanos wanted the stones for universal balance in his twisted way, and the Avengers had to prevent his plan. There were many epic battles and emotional moments throughout the movie.
