You could, but it wouldnt be easy. I dont think too many custom seat makers will touch them either.
Might contact Corbin and see if they will do it for you...
I got one recently and havent been on a ride with it yet, but Ive had them on all my previous bikes with the exception of my VTX. Ive always liked them well enough.
I did find a guy that mods the stock seat, supposed to be pretty good for not much money, and Ill probably have him mod my stock seat if he ever returns my email...
Point being, if you really wanted to, you could probably sell the Corbin and get whatever other seat you liked, or another stock seat and have it modded....and not be out much if any money.
