LOL, you are not far off. I can't remember where, but a while ago I saw an interview with some guy who did pretty much that: he opened a studio but instead of calling it yoga he came up with some 'cool' name like 'RX+fitness' or whatever (you get the idea) and marketed to 'tough guys'. He even said in the interview it was mostly yoga with some cardio, but that the whole ambiance was designed to make males feel secure doing it. He was making a killing.
