You could hole saw the sprocket if you make a jig. Just back the sprocket with something that will allow you to find center easily. Measure the sprocket hole then use a compass to mark a circle the same size on what ever you decide to use. Line up the circle with the hole and you got center. Use the bolt holes to attach it and there you go. Try to use a hole saw as close as possible to the hub, might save your ass. Personally I would use steel for the jig.
