Star Wars: Galaxy's Edge includes an area called Dok-Ondar's Den of Antiquities where you can create your own lightsaber based on one from the films, and the Disney attraction is expanding to video games, as well. In 2021, you'll be able to purchase Cal Kestis' lightsaber from Star Wars Jedi: Fallen Order.
The first video game lightsaber to be available at Galaxy's Edge, Cal Kestis' lightsaber was damaged late in the game's storyline, and it appears the version available for purchase will reflect this. It will be joined by Count Dooku's curved fencing-style saber this fall, and you'll also get to customize sabers with Ahsoka Tano's hilts and blades from The Clone Wars series.
What's interesting about the Cal Kestis saber is that it wasn't limited to a set design. As you progress through the Fallen Order story and collect more items and unlockables, you can change nearly everything on the lightsaber. This includes the hilt as well as the color itself, and this can be swapped at will to change things up. Of course, in Star Wars lore, this isn't actually possible, as the color is tied to the crystal placed inside. You can even switch between having it work as a standard saber, a Maul-style double-bladed saber, or a split saber for dual-wielding. The different configurations suit certain enemies better.
