First, just to get it out of the way: we're all stupid for not taking up golf. So it doesn't matter whether what you're trying to do is "stupid" in someone else's eyes -- if you like it, go for it.
Second, if you want the performance of a modern stunter with the looks of a Trophy Trainer, I suggest that you find a good high-performance profile (I can't suggest one -- ask), and modify the fuselage profile, rudder, and tail shape to match, while maintaining the same tail area. That should get you close.
