The burrs are entirely different. Having been through the process of looking for spares - the only ones I am aware of are Cimbali originals, no aftermarket burrs available. Are you sure the flat burrs are at fault? If you need new conicals you might consider getting a new grinder, the spares (if you can get them) are VERY expensive.
If you are lucky Chris Coffee might be able to help you, when I contacted them last year they did not have them and also were unable to source them.
