Couple problems even if San Diego would possibly have been sunk here, I expect the name of the mission would still be used here instead of Imperial. Mexicali and Tijuana seem to be in opposite sides from where the cities are in relationship to each other. Mexicali certainly wouldn’t be a name here if all of this land went independent at once. The naming convention for splitting Baja California probably wouldn’t go the same route as their went IOTL, especially since Baja already last half. Might as well just call the new state something else, if it is even worth splitting them. Guess it might in terms of providing services. Also, could you explain the logic behind the flag? I think I get what you are trying to claim, but I don’t think it works even by that logic. Granted, I am a loyal Californian so I take pride in the state flag. We all have those sort of things we just mentally like staying the same.
