This idea is more of a concept, but this idea for a crossover of Gears of War would be Star Wars: The Clone Wars. I think this has potential and it started out initially as a crossover with Mass Effect, but I figured this would be a better take.
Essentially, how this would play out is it takes place between Gears 2 and 3 and to justify the introduction of the Star Wars Galaxy, my idea is to have Anakin, Ashoka, Aayla, and the clones crash land on Sera in the episode Jedi Crash and they encounter the Gears when they go out to explore.
What happens next is instead of the Separatists attacking, the Jedi face off against the Locust and Lambent that culminates in the destruction of Vectes Naval Base. From there, Prescott goes to the Republic to ask them to help evacuate the planet of the people.
From then on, it's a montage of stranded camps being evacuated, finding a planet of their own, the Separatists attacking to "make an example" to the Galaxy that the Republic can't keep promises, but the Droid Army is essentially torn to pieces by the Seran people who then join the war, concluding that the only way to get peace is to end this war with the Republic.
Since this takes place before Gears 3, Dom will not die, Adam Fenix will also survive, but regrets not being able to aid the Locust and put a stop to the Lambent, etc, etc.
Some minor teases as well, I do plan on creating some pairings, even a teaser in the form of a Commission, but that will take some time. Pairings will appear as follow: Marcus and Anya (obviously), Dom and Sam (Sam is gonna be Dom's rock and help him accept Maria's death), Baird and Alex Brand (wish we saw more of Alex and like in Gears 4, Alex will be Baird's "special lady-friend"), and the teaser/art commission I had in mind for later in the story is Clayton Carmine and Bo-Karan Kryze.
Basically, in the Star Wars Galaxy, the Gears will essentially be more buff and muscular Mandalorians, with armor rivaling their own, scarier weapons, and just a different form of Mandalorian warriors. I may even have a rivalry form between the Serans and Mandalorians, of who is the fiercer warriors.
But in any case, I do plan to release a trailer, though it may be some time before it arrives, but I just wanted to share my idea. If you guys think I should do this idea or not is entirely up to you. Leave a review if you think I should do this, or if I should just stick with the stories I currently have.
