Corbin W650 seat

Has anyone ever tried putting a corbin w650 seat on an old KZ 750 frame? I like the looks of the Corbin Gunfighter for the W650 and would like to possibly "finesse" it onto my 78 KZ750 Twin. Just wondering if I'd be better off modeling my stock seat to look kind of like the Corbin.

i have a w650 but i had my local uphol. guy make a spare seat look like the corbin after owning one & not liklng the way it felt. he has done this to just about every bike ive owned. i get it made the way i want & much cheaper too.
