The Heritage arms rough rider and NAA mini can both be had as convertables. There are other, less common, older revolvers that share this feature made by H&R and Iver Johnson.
Ruger's single six is a nice gun, but you won't notice the difference in how they shoot between it and a rough rider until you've put 10K or 20k rounds through them.
I've shot .22lr from a .22 mag before (I forgot which cylinder I had in it. It split every single case and it was hard to eject the empies. I still wanted to shoot and .22 lr was all I had so I kept shooting. I've also considered making a sleeve for .22lr but never tried it. I think masking tape would work too.
The pressures involved with a .22 are so low that some leaking gas from a split case don't worry w much. I'd be worried more by the potential for lead being shaved from the fotcing cone or a partial barrel obstruction from a sliver of brass.
