I suppose if the two clamp bolts were to be removed ... on either side of the stem nut. And find a set of risers , where the mounting bolt goes through the inside of the new riser and threaded into the existing holes ? Rubber isolated ones maybe even better ? It might work ? You'd probably block the ignition switch and key though, with the new bar location. And the area where the original bar was clamped in, may look unfinished ?
