While it will be no real problem for consumers on a purely functional basis on an emotional level people may revolt. I like Kawasaki's for the raspy sound and rough and tough reputation they have. They may lack refinement but they have lots of personality. To rebadge a Suzuki wouldn't cut it for me. If I wanted a Gixxer I would buy a Suzuki. This will not work for the brand loyal of either mark and I don't really see the point of the same bike with two name badges.
