Swapping Front Disc Hub from small bolt to large bolt pattern

Does anyone know if you can change the front bolt pattern from the small bolt pattern (4") to the large bolt pattern (4.5") by swapping the stock front disc hub that is attached to the stock rotor to another hub with the larger bolt pattern? If it can be done what year and model hub will fit the stock rotor and where can they be purchased? Will the replacement hub change the wheel back spacing requirement?

Thanks
