Not a bad idea Markus, but all you really need is the recipes and some good brisket.
Go with just beef at first and if it's successful add the pork and chicken
Most people will argue that the real secret is in the sauce which you could order by the case online from Texas to give it a authentic flavor.
Don't forget the side dishes make it worth paying high prices, mac and cheese, cole slaw, ranch beans, Texas toast, pecan pie, etc
Picture of Texas and some big long horns should do the trick
