At least Marlin and Henry made .32 levers. Marlin was .32H&R. Henry does the 327. I don't know about cycling .32 S&W.
A T/C Contender barrel is probably available on gunbroker or ebay right now. It'll probably be .32H&R or .327. Those will fire S&W but no idea about accuracy. A Contender will satisfy any want for trying something unusual because you can always order a barrel made.
As all this involves handloading, maybe which .32 case you load doesn't matter. No big deal to ream the revolver cylinder to .32H&R neither. People were reaming 16-4s to 327 before word got out and the prices skyrocketed. Probably shouldn't go too far with that.
