Well, if you're from here, that's a bit different. I could definitely see how Louisiana/Texas might be a useful combo for someone who wants to work with the oil industry. And I agree that taking two bar exams relatively early would probably be easier than taking the second several years in the future.
Are you going to law school in Louisiana, I hope? Because (speaking from personal experience) the LA bar exam is especially brutal if you go to school out of state.
