Cocktail Recipe Idea Request: A drink with tequila and sour beer/ Berliner Weisse

Hi /r/Cocktails!I finally managed to get a real bottle of tequila here in Germany (as in 100% Agave) after checking every grocery store I visited for months. It still comes with a plastic sombrero as the lid, so it certainly doesn't take itself too seriously.I also happen to have a few bottles of Berliner Kindl Weisse (a sour beer) and I started brainstorming cocktail ideas. I love sour and carbonated things with tequila so I mixed 1 part tequila, 1 part OJ, and 3 parts Berliner Kindl over a bit of ice. It tasted quite nice, but nothing special. So, I wanted to see if anyone here could come up with something a bit more special.Thanks in advance for any creative ideas!
