Preheat a griddle over medium-high heat.
For the pork patties: Combine the pork, eggs, barbecue sauce, all-purpose seasoning, Worcestershire sauce and sazon seasoning in a bowl and mix with your hands until completely incorporated. Form into 8 patties and set aside.
For the brisket patties: Combine the brisket, eggs, steak seasoning and Worcestershire sauce in a bowl and mix with your hands until completely incorporated. Form into 8 patties.
For the burgers: Cook the pork and brisket patties on the griddle until done, 5 to 6 minutes per side. Just before removing from the heat, add the Cheddar to the brisket patties.
Assemble the burgers by placing 1 pork patty and 1 brisket patty on each potato bun. Garnish the burgers with a slice of tomato and sweet onion, a piece of lettuce, and the pickles and jalapenos, if using.
