It is going to cost you. To open something that big...if its possible, will require releveling the table at a new angle. There just isnt enough in the tip of any mouthpiece to go that far...it will become thin and at that extreme start to shorten the piece which then effects tuning. That specific mouthpiece has pretty much a zero resale value. You better like what your after...I dont think you would come close to recovering your cash if you tried.
