Au contraire mon frere. Whenever I came across a combination KFC/Long John Silver shop, my mind immediately thought JACKPOT! Whether it is fish or chicken beneath the batter is beside the point. Because if its friable and edible, its always deliciousable. Greasy fried goodness never disappoints.
What kind of combinations have you seen? I see a few Yum! combinations like KFC/Taco Bell or even KFC/Pizza Hut Express. One I like is the combo KFC/A&W because they typically have that scratch-made root beer.
