No.  USM has different torque requrements for the focussing group than Leica
permits.  Leica's focussing mounts assumes the hand will be moving it so it
doesn't have the low power consumption specs of an AF system.  This means
the LEica lens can be designed and constructed to tighter tolerances.
Simply adding AF mechanisms to existing lense will give you too much battery
drain.  Likewise a lens has to be designed with IS as an integral part of
the design.
