I would not. I would either sell it and put the money in on a new 327 mag or keep it and get the 327 mag. The 327 mag can fire most all modern 32 caliber centerfire revolver cartridges.
I don't know of any long barreled 32mag J-frames, so I would say the only recourse is to have a new barrel put on one of the 2" 32mags available today.
