If one is not tracking the Boss, you would be giving up most of the "Boss" fun. Only has 444hp compared to 412 on the GT.
0-60....Boss---4.6.......GT---5.2
1/4......Boss---12.7/113.4.....GT---13.2/109.3
Plus, repainting would only hide the real noticeable things....exhaust, grill, cage, and a big a** grin on the driver gives it away.
