Possibly, but it would require investigation to see if such a swap is easily accomplished. It can be tricky enough to install a randomly-acquired Old Model cylinder into an Old Model gun. Each instance can be a "drop in" or fraught with problems. And just because one swap works out does not mean the next one will.
