Not possible to change actually.
 * 1) Fujimi Shobo is one of the biggest publisher in Japan, do you think they would randomly sign a contract with an author without having any clause?
 * 2) Can other publisher pay Ishibumi like Fujimi can, do they have the cash to purchase the franchise from Fujimi.
 * 3) Can other studios afford to cover for the marketing used on DxD? How many publisher do you think can provide financial support to anime studios to produce anime? Publishers do spent money on finding studios to help animate their series for sales you know. And currently DxD is a franchise that anime studios are trying to get a chance to produce anime on, do you think the studio will let go of that cash cow? Can other studios afford the cash to buy DxD from Fujimi Shobo?
